		Conexant AT Commands (Advanced Users Only)
Command	(Conexant)
+ESA=a,b,c,d,	Controls operation of synchronous access mode:
e,f,g,h	a=0 specifies in transparent sub-mode, modem transmits 8-bit SYN sequence on idle.
	b=0 specified in framed sub-mode, modem transmits HDLC flags on idle (default and fixed).
	c=0 specifies in framed sub-mode, modem transmits abort on underrun in middle of frame (default);
	c=1 specifies in framed sub-mode, modem transmits flag on underrun in middle of frame, notifies
	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 character-oriented framing.
	h: not to be commanded.
+GCAP	Transmit text listing commands that provide additional modem capabilities.
+GCI=n	Set country of installation using 8-bit country code from Annex A of T.35.
+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 flow-off signal in synchronous
	access mode (default=128).
	b (10 to 5000) sets threshold (octets) below which modem generates flow-on signal in synchronous
	access mode (default=64).
	c=0 (fixed).
+PCW=n	Set modem behavior with call waiting: 1=request modem-on-hold and collect caller ID information,
	2=hang up, 3=ignore call waiting.
+PIG=n	0=enable PCM upstream negotiation, 1=disable (default).
+PMH=n	Set modem-on-hold: 0=enabled in V.92 mode (default), 1=disabled.
+PMHF	Initiate flash hook sequence when in modem-on-hold procedure.
+PMHR=n	Request modem to initiate or confirm modem-on-hold (MOH) procedure and timeout: 0=V.92
	modem-on-hold request denied or unavailable, 1 to 13 grant MOH with timeout (1=10 sec, 2=20
	sec, 3=30 sec, 4=40 sec, 5=1 min, 6=2 min, 7=3 min, 8=4 min, 9=6 min, 10=8 min, 11=12 min,
	12=16 min, 13=indefinite).
+PMHT=n	Set whether modem grants modem-on-hold (MOH) request, and MOH timeout: 0=deny V.92
	modem-on-hold request (default), 1 to 13=grant MOH with timeout (1=10 sec, 2=20 sec, 3=30 sec,
	4=40 sec, 5=1 min, 6=2 min, 7=3 min, 8=4 min, 9=6 min, 10=8 min, 11=12 min, 12=16 min,
	13=indefinite).
+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.
+VCID=n	Set caller ID reporting: 0=disable (default), 1=enable with formatted presentation, 2=enable with
	unformatted presentation.
