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 (4800–14400), V34
	(2400–33600), K56 (32000–56000), V90 (28000–56000), V92 (downstream: 28000–56000; upstream:
	24000–48000).
	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).
+FLO=a	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.
