darkfox's (dx's) guide to the Oki 900 - released by 9x in 96

This is meant to be a complete guide to the Oki 900, the #1 phone for
H/P activities. They rule! :)

The Oki 900 is not a new fone.. In fact, they have stopped making them,
but they are available used, and Oki will still sometimes repair yours
if you manage to blow it up. (just don't let them see the solder
marks inside.. hehe)

The Oki 900 has many cool functions, even without being modified.
It has all the standard stuff, like alpha-numeric memories, back-lit display,
and volume settings, and then has some unusual features, such as an
auto-answer system, that can act like a beeper. People can call it, and then
leave they number, and it will be stored in your Oki.

The Oki also has a test mode, and a very nice debug mode. [see below]
The fone can be used as a scanner, so you can monitor cellular conversations.


The testmode on the fone can be used to test various things.
You can see what cellular channel you currently are using, and see
your signal strength in hex.

To enter the testmode, power up the fone, and enter the following:

* T E S T M O D E #

You then can use the UP/DOWN volume buttons on the side of the fone
and go through a small menu.


Here's how to use the debug mode from the keypad.

Power the phone up.  Wait for PowerOn msg.  Hit 7 and 9 together.
Then hit Menu, Snd, End, Rcl, Sto, Clr. The Phone will say "good timing"
if you did it correctly. If you failed, power off the fone, and try again.

Debugger is now enabled, but phone works normally.  Hit 1 and 3
together to halt phone and enter debugger.  Everything on display
lights up.  Hit Clr, Clr till you get status display.

Now you can execute commands listed below.  For example to reboot phone
enter #, 0, 2, Snd.  Commands all start with # and end with Snd.  Some
take arguments.

You can use #25, to display memory in EEPROM, and I think once in
that command you can hit # and * to go up and down in memory, Clr to
exit.  Hex chars are entered as "*n", like *1=A, *2=B, etc.

Here is a almost complete command list:

SUSPEND     #01         Performs Initialization
RESTART     #02         Terminates the test mode
STATUS      #03         Shows current status of TRU

                         Transmit Audio Muted, Signaling tone off,
                         Autonomous timer reset, SAT off, and DTMF off

Let's say you wanted to monitor the calls on channel 100.

1. First, go into debug mode as described above.
2. Then hit #,1,2, SEND
3. Then #77 to make it louder (if you want, otherwise it is hard to hear.
4. Then press #,0,9, 100, SEND.
5. You are now listening to channel 100, press #09 (channel number),
   SEND to change channels.

- MODS -

There are many mods available for the Oki 900.

The mods are modified versions of the fones firmware, on a chip form.
Some Okis have the firmware soldered onto the board, some are socketted.

If you are lucky, yours is socketted, otherwise, I hope you are really good
with a soldering iron. :)

List Of Mods, and what they do:

4711  - a buggy mod, that supposedly let you enter up to 5
        ESNs through the keyboard, and then toggle between them.

4712  - a cleaned up version of the 4711

4713  - ???

4714  - ???

4715  - Lets you enter up to 200+ through a cable connection, or up to 5
        with the keypad. It will use each ESN only 3 times, then go to the
        next one. It makes it VERY hard to trace the fraud pattern.

Vampire - Chip that makes the Oki continually scan for ESN/MIN pairs, and
          then stores them. [this mod supposedly requires additional
          hardware mods. (EF filter?)]

 - CTEK -

 The Cellular Telephone Experimenters Kit or CTEK for short, is made by
Network Wizards. It included both software for your PC, and a special
cable to interface with the Okis proprietary data port. Unfortunately, NW
no longer has any more cables, so if you want one, you'll have to find
someone with an old CTEK, or someone that has learned to make the cable.
Making the cable yourself is not an easy feat, as it contains
microcontrollers, and other assorted electronics.

With the CTEK, you can turn any Oki, modded or unmodded, into a powerful
scanning device, that compares with high priced police equipment. You
can scan for a phone number, and then have the program turn on the audio
when that person makes a call, allowing you to tap into your targets line.

It doesn't allow you to receive ESNs though, so if your looking for a DDI,
look elsewhere.


That about covers the Oki 900. We've discussed the fone itself, the testmode,
the debug mode, mods available, and the CTEK. Now go "aquire" one and have
fun. :)

If you have any questions, look around on alt.cellular.oki.900,
alt.cellular-phone-tech, #cellular, and #9x.
