Modem Reference Information
Command | Function (Conexant) |
+MS=a,b,c,d,e,f | Select modulation (b, c, d, e, and f are optional). |
| a is the carrier (allowable rates in parentheses): B103 (300), B212 (1200 Rx/75 Tx or 75 Rx/1200 Tx), |
| V21 (300), V22 (1200), V22B (1200/2400), V23C (1200), V32 (4800/9600), V32B |
| |
| |
| b is automode: 0=disabled, 1=enabled (default). |
| c is minimum transmit (Tx) rate (bps). |
| d is maximum transmit rate (bps). |
| e is minimum receive (Rx) rate. |
| f is maximum receive rate (bps). |
+WS=n | Set PDC mode: 1=disable (default), 20=enable. |
ECC Commands
%Cn
+EB=a,b,c
+EFCS=0
+ER: a
+ER=n
+ES=a,b,c
+ESR=0
+ETBM=a,b,c
Set data compression: 0=disable, 1=enable V.42 bis and MNP 5, 2=enable V.42 bis and MNP 5, 3=enable V.42 bis and MNP 5 (default).
Select break handling (b and c are optional): a=0 — break is ignored.
b=0 — transmitted V.42
Select
Select error control protocol: NONE=error control not in use, LAPM=V.42 LAPM protocol, ALT=MNP.
Error control reporting: 0=disable, 1=enable.
Select error control and synchronous mode (b and c are optional).
a is requested mode when modem is originator: 0=initiate call with direct mode, 1=initiate call with normal mode, 2=initiate V.42 without detection phase, 3=initiate V.42 with detection phase (default), 4=initiate MNP, 6=initiate V.80 synchronous access mode when connection is completed.
b specifies fallback mode when modem is originator: 0=LAPM, MNP, or normal mode error control optional (default); 1=LAPM, MNP, or direct mode error control optional; 2=LAPM or MNP error control required; 3=LAPM error control required; 4=MNP error control required.
c specifies fallback mode when modem is answerer or specifies V.80 synchronous access mode: 1=error control disabled, use normal mode; 2=LAPM, MNP, or normal mode error control optional (default); 3=LAPM, MNP, or direct mode error control optional; 4=LAPM or MNP error control required; 5=LAPM error control required; 6=MNP error control required; 8=initiate V.80 synchronous access mode when connection complete.
Disable selective repeat option in V.42.
Handle data remaining in modem buffers on call termination (b and c are optional): a=0 — disconnect occurs immediately and buffered transmit data is discarded. b=0 — disconnect occurs immediately and buffered receive data is discarded. c=0 — modem does not attempt to deliver buffered data and discards data.
FAX Class 1
+FAE=n
+FAR=n
+FCL=n
+FCLASS=n
+FIT=n,a
+FLO=a
Data/fax auto answer: 0=disable (default), 1=enable.
0=disable adaptive reception (default), 1=enable.
Set
Set active service class: 0=data mode (default), 1=Fax Class 1, 1.0=Fax Class 1.0 mode, 8=voice mode.
Set DTE inactivity timeout n seconds after which modem goes
Set flow control type: 0=XON/XOFF and RTS/CTS flow control turned off; 1=XON/XOFF flow control in either direction; 2=RTS for flow control of modem by DTE, and CTS for flow control of DTE by modem.
