Function (Conexant)
Controls operation of synchronous access mode:
a=0 specifies in transparent
b=0 specified in framed
c=0 specifies in framed
d: not to be commanded.
e=0 specifies CRC generation and checking disabled (default and fixed). f=0 specifies NZRI encoding and decoding disabled (default and fixed). g=255 sets the octet value used in
h: not to be commanded.
Transmit text listing commands that provide additional modem capabilities.
Set country of installation using
Report modem manufacturer.
Report modem model.
Report modem version, revision, or date.
Transmit text identifying the device.
Report modem model serial number.
Set operation of local flow control between DTE and modem.
n =method DTE uses to control data flow from modem: 0=none, 1=XON/XOFF on transmitted data, 2=Circuit 133 (Ready for Receiving) (default).
m =method modem uses to control data flow from DTE: 0=none, 1=XON/XOFF on received data, 2=CTS/RTS (default).
Report local port rate: 0=disable, 1=enable.
Set data rate at which the modem accepts commands when connected: 0 (allows operation only at rates automatically detectable by modem), 2400, 4800, 9600, 19200, 38400, 57600, or 115200.
Sets transmit flow control thresholds (b and c are optional):
a (20 to 7000) sets threshold (octets) above which modem generates
b (10 to 5000) sets threshold (octets) below which modem generates
c=0 (fixed).
Set modem behavior with call waiting: 1=request
0=enable PCM upstream negotiation, 1=disable (default).
Set
Initiate flash hook sequence when in
Request modem to initiate or confirm
Set whether modem grants
Use Short Phase startup procedures: 0=enable V.92 Short Phase 1 and 2 (default), 1=enable Short Phase 1 only, 3=disable.
0=modems decide whether to use short startup procedures, 2=use full startup procedures on all subsequent connections.
Set caller ID reporting: 0=disable (default), 1=enable with formatted presentation, 2=enable with unformatted presentation.
