Command | (Conexant) |
|
|
+ESA=a,b,c,d, | Controls operation of synchronous access mode: |
e,f,g,h | a=0 specifies in transparent |
| b=0 specified in framed |
| c=0 specifies in framed |
| c=1 specifies in framed |
| DTE. |
| 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. |
+GCAP | Transmit text listing commands that provide additional modem capabilities. |
+GCI=n | Set country of installation using |
+GMI | Report modem manufacturer. |
+GMM | Report modem model. |
+GMR | Report modem version, revision, or date. |
+GOI | Transmit text identifying the device. |
+GSN | Report modem model serial number. |
+IFC=n,m | 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). |
+ILRR=n | Report local port rate: 0=disable, 1=enable. |
+IPR=n | 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. |
+ITF=a,b,c | Sets transmit flow control thresholds (b and c are optional): |
| a (20 to 7000) sets threshold (octets) above which modem generates |
| access mode (default=128). |
| b (10 to 5000) sets threshold (octets) below which modem generates |
| access mode (default=64). |
| c=0 (fixed). |
+PCW=n | Set modem behavior with call waiting: 1=request |
| 2=hang up, 3=ignore call waiting. |
+PIG=n | 0=enable PCM upstream negotiation, 1=disable (default). |
+PMH=n | Set |
+PMHF | Initiate flash hook sequence when in |
+PMHR=n | Request modem to initiate or confirm |

| 12=16 min, 13=indefinite). |
+PMHT=n | Set whether modem grants |

+PQC=n | Use Short Phase startup procedures: 0=enable V.92 Short Phase 1 and 2 (default), 1=enable Short |
| Phase 1 only, 3=disable. |
+PSS=n | 0=modems decide whether to use short startup procedures, 2=use full startup procedures on all |
| subsequent connections. |
