Format:

AT [cmds] %Q1 [cmds]

Description:

Displays information on the connection

Connection

Display

V.32/V.32bis

EQM: (same as %Q)

Receive Level: (same as %L)

Transmit Level: (current TX level in dBm)

V.FC/V.34

Far Echo Delay: (round trip far end echo delay in ms)

Far Echo Level: (signal Strength of far echo in dBm)

Pre-Emphasis Filter: (filter in use to normalize the lines frequency response as per V34 DSP specs. and ITU V.34 specs.)

V.34 only

SNR: (signal to Noise ratio measured during the line probe, in dB)

Normalized Bandwidth: (The -3dB roll off points after the pre-emphasis filter is applied. This is not the same as the usable audio band-width since the signal has been heavily processed prior to this measurement. This range determines the maximum symbol rate the line will support.)

Baud rate: (symbols per second on the connection)

Transmit Carrier: If the symbol rate is below 3429 there are two available carrier frequencies. (A high carrier and a low carrier.) The actual frequency of the carriers varies with the symbol rate. "high" or "low" are the only items displayed.

Received Carrier: same as above on received carrier

SC-REGISTERS

Type:

Register

Format:

AT [cmds] SCn=x [cmds]

Description:

Each register "pair" holds the value for each setting. To set a value, divide the setting by 256. The integer goes in the second register, while the remained goes in the first. (A setting of 516 would convert to 2 Remainder 4, and could be set by sending ATSC0=4SC1=2 to the modem.) Settings are in 1/100ths of a second. Setting SC0=22 & SC4=22 allows FAST BUSY to also be detected as BUSY.
