I. INTRODUCTION

     This article is an attempt to cover the essential concepts of
     the typical bulletin board so that a new user can quickly become
     familiar with its  function, features, and use.

     Presumably, most people learn about bulletin board systems from
     simple trial and error exploration, or perhaps from having
     watched a more experienced user.  This is a slow process,
     however.  So much so that many people mistakenly believe that
     one must know a great deal about computers and data
     communications to understand and use a bulletin board system
     (BBS).

     But, while bulletin board systems do offer a great many
     educational and useful services to help the new computer user
     make better use of his computer, regrettably there isn't much
     available to help the new user access these services.  My hope
     is that this article will present a few general concepts about
     bulletin boards while at the same time emphasizing the need for
     general information about bulletin boards.

     The availability of such information can make life easier for
     both bulletin board owner and the new user.  By listing the
     necessary steps to print such files, a new user can quickly
     become familiar with the necessary concepts.  Under some
     bulletin board systems these files could be made menu items.  Or
     the files might be distributed via user's group on paper.  But
     even if such files are placed on a bulletin board with no
     explanation, I believe that the new user who finds them will
     still benefit as there is considerably more to using a bulletin
     board than simply connecting up and listing a text file.

     Of course, I base this work on the accomplishments of others.
     Notably, Tom McCormick of Houston recognized early on that the
     new user needed some basic knowledge to use bulletin boards
     effectively.  His RCPMDATA.17A, developed in 1982, is the only
     document I found on any bulletin board that even came close to
     trying to answer a first timer's typical questions.  While this
     article is surely not intended as a replacement for Tom's work,
     I have borrowed heavily from it as I made my own contributions.


     II.  BASIC COMPUTER CONCEPTS

     Before explaining what bulletin boards do, perhaps it would be
     best to first explain some key computer concepts.

     A FILE on a bulletin board system is a collection of related
     records which may be composed of text, executable computer code,
     or other information.  Files may be sent to the bulletin board
     or received from the bulletin board for personal use.  For
     example, a memo, a table of numbers, or an accounting program
     would each be considered a file.

     A FILENAME is simply a name given to a file which uniquely
     identifies it apart from other files.  Most systems use
     filenames comprised of one to eight non-space characters with an
     additional optional "filetype" comprised of up to three
     characters.  The filetype is generally separated from the rest
     of the filename by a period (.).

     A DIRECTORY is a listing of files (by filename) that share the
     same space on a computer system.  A computer system may have
     more than one directory so that files may be grouped according
     to the type of file.  For example, accounting files could be
     grouped together in one directory while inventory files could be
     put in another directory to keep them separate.

     SOFTWARE can generally be conceived to be the computer programs
     that tell the computer how to do something.  It could be an
     application, a game, a communications program, -- almost
     anything.  Because there are different computers, there are also
     different kinds of software.  It is important to understand that
     just because some piece of software will run on SOME machine,
     this does not necessarily mean that it can work on YOUR machine.

     Computer programs (software), like text and other forms of
     information, generally take the form of a file in a directory.

     An OPERATING SYSTEM is an essential computer program (software)
     that coordinates all the activities on a given computer system.
     It manages resources and generally handles the flow of data
     inside the computer system.  Although all operating systems
     perform the same basic functions, there are different brands
     having various features.  Because software is generally created
     to work with a specific operating system, it is important to
     know which one your computer uses.

     Common microcomputer operating systems include CP/M-80, CP/M-86,
     MS-DOS, TRSDOS, PC-DOS, and PRO-DOS.  Some bulletin board
     systems are set up just for a specific machine or operating
     system.  Because computers are made using different technologies
     and operating systems, one should not expect software written
     for one machine (or operating system) to work on another.
     Surely, the best BBS is one offering software compatible with
     one's own computer.

     A MODEM is a piece of computer equipment that connects a
     computer to the telephone system for purposes of communicating
     with other remote computers.  It may be built into the computer
     or come as a physically separate option.  It is important to
     note that a modem alone is not sufficient for communication to
     occur.  Communications software must be present on both computer
     systems.  And like the modem, this may come with the computer or
     be a separate option.

     Modems transfer information at different rates.  This rate is
     usually measured in bits per second (BPS) and is often referred
     to as the modem speed.  Rather than refer to the modem speed in
     terms of bits per second, some manufacturers prefer to use a
     technically similar term called BAUD.  For most microcomputer
     communications these days, BAUD and bits per second are
     virtually interchangeable terms.

     Common modem data transfer rates are: 300, 1200, and 2400 baud.
     Communicating computers must use the same rate of speed to
     communicate with each other.  Generally speaking, a modem
     supporting 1200 baud will also support 300 baud as well.  And
     most 2400 baud modems will recognize 1200 and 300 baud.
     However, if you want to communicate with a BBS that supports
     only 300 baud, you cannot communicate with it at 1200 or 2400
     baud even though you may have a modem which supports these
     speeds.

     Besides the rate of data transfer, modems can be set up for a
     variety of other communications parameters such as the number of
     stop bits, data bits, the type of parity used, and the duplex.
     It isn't really necessary for the new user to fully understand
     these terms, but just as both communicating computers must
     support the same baud rate, so also must they both support the
     same other communications parameters.  Most bulletin board
     systems today have standardized around 8 data bits, 1 stop bit,
     no parity, and full duplex.


     III.  BASIC BULLETIN BOARD CONCEPTS

     A BBS or BULLETIN BOARD SYSTEM is a remote computer running
     special communications software that allows unattended
     electronic mail messaging and file transfers for remote users
     via phone lines.  This means that most bulletin board systems
     have two components: a message area for personal messages and /
     or general bulletins, and a file area for files that are
     available for copying.

     USERS call the BBS computer using their own computer, modem and
     communications software.  The remote BBS modem answers and the
     BBS software communicates with the user's system.

     The SYSOP or SYStem OPerator is the person who runs and
     maintains the bulletin board system.  This benevolent person has
     offered his valuable time and his costly computer equipment for
     use as a bulletin board by the public.  The SYSOP may or may not
     be available when the user uses the BBS.  Bulletin board systems
     are usually unattended (that's the whole idea).

     People use bulletin boards for a variety of reasons.  A
     corporation may keep track of its field sales staff's daily
     accomplishments.  A computer hobbyist may keep up to date with
     what is happening on the local microcomputing scene.  A
     consultant may be interested in software that will help him in a
     particular area, such as geology.  Sometimes a BBS may be used
     to get in touch with a very busy person.  Or to simply copy free
     and useful software.  Traditionally, use of a bulletin board
     system boils down to

     1) getting in touch with one or more people,

     2) getting information, or

     3) copying files of software.

     Of course, today there are many other communications options.
     Voice telephone, the post office, and overnight mail services
     are all competing alternatives.  For non-priority
     communications, the mail may be better than any BBS.  Likewise,
     for no-delay interactive communication, a voice phone call is
     clearly superior.  Bulletin boards are successfully used when
     the information to be transferred is time dependent or when the
     availability of frequently changing information is important.

     For example, a company could send out frequent updates of a
     certain file by diskette through the mail to all subscribers in
     the organization, even those who do not currently have a present
     need for the information.  There are postage and mailer costs
     and quite a bit of labor costs -- both on the sending and the
     receiving end.  If this file was maintained on a bulletin board,
     the file would be instantly made available to everyone and only
     those who need it would call and copy it to their system.  It's
     fast, and efficient.

     Bulletin board systems may be entirely private for only company
     or club personnel.  Others may charge a fee for access either
     because they are so heavily used, or because they require
     membership like a club.  Many are free.


     IV.  LEGAL CLASSES OF SOFTWARE

     Software can come with various legal restrictions on it's use.
     Most BBS software can be freely copied and distributed to others
     as long as the distribution is not for personal gain or profit.
     The user should always be wary and respectful of the author's
     intentions, otherwise you may receive or distribute software
     illegally.  "Software piracy", or stealing software to which you
     are not entitled, can result in expensive lawsuits, time spent
     in jail, and nasty fines.  Obviously, you should understand the
     differences between the various classes of software and not take
     them lightly.

     By definition, software in the PUBLIC DOMAIN is not copyrighted,
     cannot be copyrighted, and is owned by the public.  Public
     domain software may be bought, sold, or distributed to anyone by
     anyone for any use whatsoever.  Many bulletin board systems make
     such software available on their systems for use by anyone who
     wants it.  If software does not display a copyright notice when
     executed, then it is by default public domain.  This type of
     software is the easiest to identify.

     FREEWARE is copyrighted software that authors permit to be
     freely distributed as long as it is used personally and not sold
     for profit.  There is a growing amount of this type of software
     on bulletin board systems.  Early bulletin board contributing
     programmers got tired of entrepreneurs capitalizing on their
     public domain investments.  This kind of software is definitely
     NOT public domain.  If the software displays a copyright notice,
     but does not specifically state that it may be freely
     distributed for noncommercial personal use, then beware -- it
     may not even be freeware!

     USER SUPPORTED SOFTWARE is generally freeware but the author
     requests that the user voluntarily remit a nominal fee if the
     software is found to be useful.  This is so that good
     programmers can defray a few expenses and continue to produce
     good software for everyone to use.  This type of software is
     sometimes called SHAREWARE.

     COMMERCIAL SOFTWARE is copyrighted software for licensing.  It
     is called PROPRIETARY because the programmer reserves all rights
     to the software unto himself.  This type of software is not
     given away or even sold, but paying customers are licensed to
     use it.  Some bulletin board systems are set up to dispense such
     software so that the user can get the software quickly (after
     the SYSOP has obtained the user's credit card payment).

     Sometimes bulletin board systems offer DEMO SOFTWARE.  This is
     commercial software that is limited in some way so that users
     can try the software before licensing.  If the software is found
     to be what the user wants, he must pay to receive a full
     featured version of the software.

     It is wise to thoroughly inspect files copied from bulletin
     board systems to discover the software's legal status.  If it
     displays a copyright, it is NOT public domain.  And if the
     copyright owner fails to provide an explicit licensing policy
     statement, you should consider the software commercial and
     proprietary.  Freeware and user supported software will always
     be clearly identified.  Just because you copied the software
     from a BBS or even a well meaning friend does NOT mean that the
     software is okay to use.  It could well be proprietary and your
     use could be prosecuted as theft.


     V.  BASIC FILE TRANSFER CONCEPTS

     DOWNLOADING is the process of copying software or other files
     from the BBS to the user's computer.

     UPLOADING is the process of copying software or other files from
     the user's computer to the BBS.

     These two terms are often confusing to new users, but they can
     be easily remembered by visualizing the remote BBS as
     "upstairs".  Thus, sending the BBS a file must be an UPload,
     while receiving a file from a BBS would be considered a
     DOWNload.

     A PROTOCOL is generally conceived to be a communications
     technique designed to allow the reliable and coordinated
     transfer of information between two remote machines.  By using
     such a method for file transfer, information in transit becomes
     relatively impervious to the phone line noise, temporary
     interruptions, and electrical "hits" that typically alter data
     in transmission.

     Basically, there are two problems in data communications:
     missing data and changed data.  And this can occur quite
     frequently with data sent over ordinary phone lines.  According
     to one Bell System survey, an average of 1.46 characters was
     found to change with every 10,000 characters sent.  And, an
     average of 6.81 characters was found to be lost.  While 10,000
     characters might seem like a lot, it is a small data transfer.
     This is why there are error detecting protocols and why they
     MUST be used if the data has any value.

     XMODEM (or Christensen) protocol has become the defacto standard
     of microcomputer data communications.  Nearly all bulletin
     boards offer this protocol (perhaps in addition to others).  The
     XMODEM technique sends the data in "packets" of 128 characters.
     In this fashion, if an error is detected, the "bad" packet can
     be sent again instead of the entire file.  This strategy works
     so well that all popular microcomputer protocols use a similar
     technique.  Other common protocols for micros include KERMIT,
     TELINK, and MODEM7.  The user's communications software MUST use
     a protocol recognized by the BBS in order for files to be sent
     error free.


     VI.  BULLETIN BOARD SECURITY

     Most bulletin board systems require new users to select a
     PASSWORD and to register before full access to the system will
     be allowed.  The information provided is subject to "validation"
     by the SYSOP so it may be a couple of days before the user can
     be given normal access privileges.  The SYSOP must verify that
     the information provided is factual for reasons of security.

     Because SYSOPS must deal with the unscrupulous, password
     protection is used to refuse service to known abusers of the
     system.  This also reduces the SYSOP's legal liability in the
     event that libelous or profane messages result in litigation.
     And it also protects innocent users from potentially
     embarrassing messages being sent in their name.

     In the beginning, bulletin boards were subject to crashing or
     invasion by dishonest people desiring to steal commercial
     software.  Today bulletin board systems are more resistant, but
     other offenders have emerged.  Here are some definitions of
     bulletin board abusers by BYTE magazine's Steve Ciarcia
     (December 1985):

     "Phreaks defraud the telephone company of toll charges through a
     variety of schemes.  Pirates use bulletin boards to exchange
     information on how to illegally duplicate copyrighted software.
     Worms and crackers break into other computers to access
     confidential files and destroy information."

     Needless to say, SYSOPs have taken steps to try and combat these
     people.  Abide by the rules provided by the BBS SYSOP and
     recognize that the policies he enforces are there for your
     protection and in your best interest.


     VII.  BULLETIN BOARD USE

     Many bulletin board systems can sense the baud rate of your
     modem automatically, but older 300 and 1200 baud systems may
     require that the return key be pressed a couple of times.  Some
     of the newer 2400 baud modems require that you press the space
     bar a couple of times before a link can be established.

     To make more effective use of space on a BBS, files are
     generally stored compressed to 60% - 75% of their original size.
     This also allows for much faster downloading.  You should
     familiarize yourself with the utilities used for this purpose on
     the target BBS as they will be required to decompress the
     programs you download before they can be used.

     Because there are so many files available, SYSOPS generally use
     LIBRARY utilities to organize one or more related files into a
     single library file.  You should familiarize yourself with the
     library utilities used on the target BBS so that you will be
     able to de-library files after downloading.  Some of these
     utilities automatically compress the files in the library and
     some do not.

     It would be a good idea to practice file transferring with a BBS
     in your local calling area before going to a distant BBS.  If
     you do not have a local BBS, practice with an experienced user
     the first time you call long distance.  Of course, long distance
     carriers such as MCI and SPRINT may be able to save you money.

     Many SYSOPS have far more files than are online at any time.
     Many will accept requests on their bulletin board to place
     requested files you need online for you.  You might leave a
     message for the SYSOP asking if he has the file you need or if
     he knows where you might be able to get it.


     VIII.  COMMONLY OBSERVED BBS CONVENTIONS

     On many bulletin board systems, there is often an XMODEM program
     (which uses the XMODEM protocol) which is used to download and
     upload files to and from users.  The BBS needs the XMODEM, not
     the user, and it is specific to the BBS used.

     On some systems, you may find program files with an .OBJ
     filetype.  This is a convention on some older bulletin board
     systems to prevent the user from actually executing the program
     on the BBS computer.  Files downloaded with this filetype will
     likely need to be renamed after downloading to have an
     executable filetype.

     There are other filetype conventions.  For example, files ending
     in .TXT are generally text files.  It has also become a
     convention for documentation files to have the filetype .DOC on
     most bulletin board systems.  Try to look at the .DOC file to
     learn the purpose or restrictions of a program before you bother
     to download it.

     The traditional programs for file compression and decompression
     are the SQ (Squeeze) and USQ (unsqueeze) utilities.  Squeezed
     files are identified by the letter Q in the 2nd position of the
     filetype; for example, MODEM7.DQC must be run through USQ to
     produce the readable MODEM7.DOC file.

     The traditional library utility is the ARC program, but a second
     utility called ZIP is becoming more popular in some sections of
     the country at this time.  These utilities store multiple
     related files together as a single file.  A libraried file is
     easier to organize and manipulate than a series of smaller
     files.  Files libraried with ARC will have a .ARC filetype.  And
     those with a .ZIP filetype have been produced with the ZIP
     utility.

     Some bulletin board systems have a command or option which will
     list files that have been added or deleted since a certain date.
     Using this feature can also save time.  The traditional command
     is WHATSNEW, but other names for this function may be used (such
     as NEWIN) depending on the BBS used and the SYSOP's preference.

     The message system on some systems will be an executable program
     that exits to the operating system level for file transfers.
     This program is traditionally called "RBBS" (Remote BBS).  Other
     systems never let the user access the operating system, but
     operate using a series of menus and prompts.

     Systems that allow you access to the operating system level for
     downloading generally use a program called BYE that logs you off
     the BBS and resets the system for the next caller.  If you are
     hopelessly hung up in a loop, then just hang up and call back in
     thirty seconds or so; the systems will almost always reset after
     they sense the loss of the phone carrier signal.  For menu or
     prompt driven bulletin board systems Q(uit) or G(oodbye)
     generally will log you off the system.


     IX.  BULLETIN BOARD ETIQUETTE

     Do not despise things that are free.  It is a curious fact in
     the computer world that value bears almost no relation to price.
     Some of the best programs for personal computers are in the
     public domain.  They often work better and are better supported
     than software costing hundreds of dollars.  And, in terms of
     documentation, many commercial programs do not even come close.

     Many bulletin board systems operate from private home
     telephones...  be courteous and call only during the posted
     operating hours.

     Many systems have time limits (usually 1 hour in prime time).
     Some communications programs have a CAPTURING or LOGGING feature
     which records everything that passes between the two computers.
     This capability can be used to make more effective use of the
     allotted time by allowing the BBS directory of available files
     to be captured and read later after ceasing communications with
     the BBS.  After you hang up, you can print it off, mark the
     files you want, and then call back.

     Of course, realize that there are other people who want to use
     the system.  You will want to limit your calls so that others
     can enjoy the system.  Don't overstay your welcome.

     If you discover a problem with the host system, report it to the
     SYSOP by leaving a message on that bulletin board, or by
     contacting him directly to tell him about it.  He may never know
     if someone does not tell him.  This is an easy way to repay for
     the use of that system, and it will be appreciated by the SYSOP.

     This should not be necessary to say, but it is.  Do NOT use
     these systems for commercial messages, ethnic jokes, political
     commentary, heavy- breathing messages, obscenities, and the
     like.  Users are of all ages and persuasions, and restraint (or
     maturity) will be appreciated by all.  If you know of anyone
     abusing a system, please discourage it, or report it to the
     SYSOP.

     It should also not be necessary to say that acts of software
     piracy on bulletin board systems are generally frowned upon.
     You should not insult your SYSOP's intelligence by uploading
     proprietary software or asking the SYSOP to make commercial
     software available to you without proper licensing.  Those who
     draw their own integrity into question are likely to have their
     access privilege taken away promptly.  SYSOPs often make such
     information available to other area SYSOPs so other bulletin
     board systems may refuse your request to access their systems.
     Play nice in the sandbox and others will play nice with you.  Be
     naughty and you are likely to find sand in your eyes.

     While it may appear cute to register under an alias, handle, or
     silly name, this is not considered kosher by most SYSOPs as it
     makes it harder to prevent abuse of the BBS.  Users attempting
     to do so may find that the SYSOPs are reluctant to allow access
     to them.  It is only fair that the user use his real name in
     communicating with the BBS.  Those who fail to observe this rule
     will likely get their access privileges revoked.

     While message areas may be used to give a plug for your company
     or product, you should not abuse this privilege.  One
     advertisement per BBS is generally considered tolerable,
     although some systems are restrictive.  Consult the policy
     statement on the BBS or ask the SYSOP to avoid stepping on any
     toes.

     If you have difficulty using a bulletin board and you are a new
     user, make every effort to find and read the HELP files on the
     system (if any) before you ask for help from the SYSOP.  SYSOPs
     have better things to do than to answer questions that could
     have been answered if the user would just read.  SYSOPs are
     generally busy people so make sure your question is not of
     trivial import.  While many SYSOP's will be glad to help you
     with a specific question, it is NOT their job to educate or
     train you.

     The bulletin board philosophy evolved originally to aid computer
     people in their quest to keep in touch with each other and help
     each other out.  It was worth the effort for a programmer to
     spend his time developing a program and share his efforts with
     others in hopes that they would share with him what they had
     developed.  Some bulletin board systems still operate this way.
     In a way, it is similar to the academic "Publish or Perish"
     philosophy.  The idea was that he who does not contribute and
     becomes a taker all the time should not be allowed access.

     Luckily for non-programmers, this ideology has since been
     modified for most bulletin board systems.  While non-programmers
     may not be able to contribute original programs, they can act as
     carriers.  Uploading a good program onto a BBS that does not
     have that file will be appreciated.  And there are enough
     bulletin board systems around to make this a fairly easy process
     for the non-programmer.

     It is a good idea to keep a notebook on the files you send and
     receive from bulletin board systems.  In this fashion you can
     easily track your ratio of uploads to downloads.  Remember, new
     files do not spontaneously grow on bulletin board systems; they
     are put there by users.  And as a user, you are expected to
     contribute to the BBS store of files from time to time.  Some
     SYSOP's are very strict about this and will deny further access
     if you do not contribute.  Most simply want some kind of
     occasional contribution, but some SYSOP's want to see an upload
     for every n files downloaded.  Check with your SYSOP about his
     upload policy, and keep him happy.

     You may be able to upload a number of files and save money at
     the same time if you are sending the files to a long distance
     BBS.  Check with the SYSOP to see if he can read your diskette.
     For a number of files, it may be cheaper to send a disk than to
     upload the files using the phone system.  And if you plan to
     send the SYSOP a great deal of files (much more than your upload
     / download ratio requires), you may be able to talk the SYSOP
     into returning your diskettes (via self addressed stamped
     envelope) with some files you want from him.  Understand,
     however, many SYSOP's simply do not have the time for such
     things so check with him BEFORE you send a diskette.

     X.  TYPES OF BULLETIN BOARDS

     Bulletin board systems generally come in two different
     varieties: 1) those that allow access to the operating system
     level, and 2) those that can isolate a user from the operating
     system entirely.  Some types of bulletin board systems have
     become popular and somewhat standardized as a result.  Such
     systems include TBBS, ROS, FIDO, CBBS, RBBS, Z-NODE, and Goliath
     systems.  But not all bulletin board systems are so
     standardized; many are of custom manufacture.

     Many are menu driven in nature so that even the new user can
     easily use them.  Historically, this has not always been the
     case.  And there are still many bulletin board systems that are
     less user oriented.  Probably one of the most popular such
     systems is the RBBS which can leave users at the operating
     system level to fend for themselves.  If the BBS has not been
     set up so that new users are told what to expect, it can be a
     frustrating experience.  But, the RBBS is a bulletin board
     classic and there have been many offshoots and takeoffs on the
     same general theme.  And because it has been such an influential
     system, it is worth going over the traditional commands.

     Typically, the RBBS style system has a messaging system as the
     usual entry point into the system once connection is made and a
     proper password is given.  In the messaging system there is
     usually an option to exit to the operating system.  Once at the
     operating system level, it helps if the user knows something
     about the operating system used.

     The drive identifier and command prompt will appear and
     generally the first thing a user will want to do is list the
     directory of files available.  This is usually done with the DIR
     command.  Files that are seen to be of interest will generally
     have a .DOC file somewhere that describes the file(s) in
     question.  The .DOC files, and any other text files, may be
     listed by using the TYPE command.  TYPE generally can read
     compressed or normal files.

     Changing directories is usually done by entering the name of the
     drive identifier, followed by a colon (A:, B:, C:, etc.).  On
     CP/M operating systems there is a USER command which enables a
     user to change from one user level on a drive to another.  User
     levels are analogous to floors in a building and the USER
     command serves as a kind of elevator.  Some systems have
     simplified the process by combining the drive and user area
     number into one command, and instead of using the USER command,
     you simply enter the drive and user area number followed by a
     colon (A4:, B13:, B2:, etc.).

     Some systems make this process of changing directories even
     easier by using the SECTION command.  SECTION generally assigns
     all directories a name instead of a drive and user number.
     SECTION alone lists the possible areas, and SECTION with an area
     name takes you to the area.

     Sometimes in using a bulletin board system, a series of letters
     will be presented in the following fashion:

     COMMAND: (C,E,F,G,K,R,S,N,b,m,p,t,w,x,?):

     Many BBS users are so familiar with the software's operation
     that they do not need a verbose list of commands.  Since most
     users are experienced users, some bulletin board systems leave
     the verbose listing of the various commands as an option.  To
     see it, enter a question mark (?).  In fact, many computer
     systems will provide information when the question mark key is
     pressed.

     Of course, it is always possible that the new user could get
     lost or not know how to proceed.  On many systems there is a
     HELP command which will provide some information about one or
     more topics.  In the event that the HELP command is not
     available or does not explain away the problem, the SYSOP can be
     alerted by using the CHAT command.  This command beeps the BBS
     bell to alert the SYSOP.  If he is available, he will respond by
     typing a message to you on the BBS.

     Of course, the primary objective of accessing the operating
     system is to generally copy files to your machine.  This is
     traditionally done with the XMODEM program, although there are
     several other lookalikes circulating these days (KMD is one such
     XMODEM clone).  XMODEM is the communications program that will
     send a file to your communications software using an error
     detecting scheme.  XMODEM is capable of receiving files as well
     as sending them, but the new user generally is only interested
     in sending.  This is done by entering XMODEM S filename, where
     filename is the name of the file you want to copy.

     After the session, to log off the BBS, there is a command called
     BYE which terminates the communication and hangs up the phone.
     Most systems will tolerate your just hanging up, but it is
     probably best to use the BYE command anyway, just in case.
