Command

(Conexant)

 

 

+MS=a,b,c,d,

Select modulation (b, c, d, e, and f are optional).

e,f

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),

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

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).

+EB=a,b,c

Select break handling (b and c are optional):

 

a=0 — break is ignored.

 

b=0 — transmitted V.42 L-SIGNAL will not indicate break signal length.

 

c=0 — break is not delivered to DTE.

+EFCS=0

Select 16-bit FCS specified in V.42.

+ER: a

Select error control protocol: NONE=error control not in use, LAPM=V.42 LAPM protocol,

 

ALT=MNP.

+ER=n

Error control reporting: 0=disable, 1=enable.

+ES=a,b,c

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.

+ESR=0

Disable selective repeat option in V.42.

+ETBM=a,b,c

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

Data/fax auto answer: 0=disable (default), 1=enable.

+FAR=n

0=disable adaptive reception (default), 1=enable.

+FCL=n

Set loss-of-carrier delay in units of 100 ms (n=0 to 255).

+FCLASS=n

Set active service class: 0=data mode (default), 1=Fax Class 1, 1.0=Fax Class 1.0 mode, 8=voice

 

mode.

+FIT=n,a

Set DTE inactivity timeout n seconds after which modem goes on-hook (a=0) or DCE goes on hook

 

(a=1).
