AT Commands
F-4 AT Commands
\An Maximum MNP Block Size
Sets maximum block size for MNP stream link connections.
0 = Sets block size up to a maximum of 64 characters
1 = Sets block size up to a maximum of 128 characters
2 = Sets block size up to a maximum of 192 characters
3 = Sets block size up to a maximum of 256 characters
-AnAuto-Retrain Threshold
Sets the maximum number of times the modem can auto-retrain, where n = 0 to 255
(Default = 0).
Bn ITU-T/Bell Mode
0 = Uses ITU-T V.22 and V.21 standards at 1200 and 300 bps
1 = Uses Bell 212A and 103 standards at 1200 and 300 bps
$Bn Serial Port Bps Rate
Where n = 75, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 bps
Sets the serial port bps rate when issued.
%Bn Modem Port Bps Rate
Where n = 75, 300, 600, 1200, 2400, 4800, 7200, 9600, 12000, 14400, V14400, 16800,
19200, 21600, 24000, 26400, 28800, 33600 bps
When you enter this locally, sets the modem port bps rate. Downshifting can still take
place.
When you enter this during a remote access session, the new modem port bps rate does
not take effect until the current connection ends.
If %G0 is set, an AT issued locally causes the modem port speed to match the serial
port speed, regardless of any previous %B setting.
If %G1 is set, the modem speed is changed only when you enter a %Bn command.
Entering %F1, %F2, or %F3 causes the modem to change to either split speed or 1200
bps.
