Modem Reference Information
Command | Function (Conexant) |
Mn | Activate speaker: 0=off, 1=on during handshaking and off when receiving carrier (default), 2=always |
| on, 3=off when dialing and receiving carrier, on when answering. |
N0 or N1 | Included for compatibility only; returns result code. |
On | 0=go |
P | Force pulse dialing. |
Qn | 0=enable result codes to DTE (default), 1=disable. |
Sn | Select |
Sn=v | Set default |
T | Force DTMF dialing. |
Vn | Report result codes: 0=short form (terse), 1=long form (verbose) (default). |
W0 | Report DTE speed (default). |
W1 | Report line speed, error correction protocol, and DTE speed. |
W2 | Report DCE speed. |
W3 | Report DCE speed and error correction protocol. |
X0 | Report CONNECT result code on connecting. Dial tone and busy detection not reported. |
X1 | Report CONNECT <text> result code on connecting. Dial tone and busy detection not reported. |
X2 | Report CONNECT <text> result code on connecting. Dial tone and busy detection not reported. |
X3 | Report CONNECT <text> result code on connecting. Dial tone not reported, busy signal reported if |
| detected. |
X4 | Report CONNECT <text> result code on connecting. Dial tone and busy signal reported if detected |
| (default). |
Z | Reset to default configuration. |
+DR: a | Select error control protocol: NONE=no data compression, V42B=42bis in both directions, ALT=MNP |
| 5 compression. |
+DR=n | 0=disables extended format "+DR:" intermediate result code, 1=enables. |
+DS=a,b,c,d | Controls V.42bis data compression function (b, c, and d are optional): |
| a sets direction(s) of data compression function, seen by DTE: 0=negotiated, no compression; 3=both |
| directions (default). |
| b=0 specifies modem does not disconnect if V.42bis is not negotiated by remote modem as specified |
| by a. |
| c sets maximum number of dictionary entries (2048) that should be negotiated. |
| d sets maximum string length (32 bytes) to be negotiated. |
+DS44=a,b,c,d, | Controls V.44 data compression function (b, c, d, e, f, g, h, and i are optional): |
e,f,g,h,i | a sets direction(s) of data compression function, seen by DTE: 0=negotiated, no compression; |
| 1=transmit only; 2=receive only; 3=both directions (default). |
| b specifies whether modem disconnects if V.44 not negotiated remote DCE as specified in a: 0=do not |
| disconnect (default), 1=disconnect. |
| c: 0=stream method (default), 1=packet method, 2=multi=packet method. |
| d (256 to 2048) sets maximum codewords to be negotiated in transmit direction (default=2048). |
| e (256 to 2048) sets maximum codewords to be negotiated in receive direction (default=2048). |
| f (32 to 255) sets maximum string length to be negotiated in transmit direction (default=32). |
| g (32 to 255) sets maximum string length to be negotiated in receive direction (default=32). |
| h (2048 to 4096) sets maximum size of history buffer to be negotiated in transmit direction |
| (default=4096). |
| i (2048 to 4096) sets maximum size of history buffer to be negotiated in receive direction |
| (default=4096). |
