Chapter 3 – Fax Class 2 Commands

Current Sessions Parameters

Class 2.1	+FIS=
Write Syntax:	+FIS=VR,BR,WD,LN,DF,EC,BF,ST,JP
Values:	See Table 3.5
Default:	1,3,2,2,0,0,0,0,0
	The +FIS parameter allows the host to sense and constrain the capabilities used for
	the current session. The modem uses +FIS to generate DIS or DTC messages
	directly, and uses +FIS and received DIS messages to generate DCS messages.
	The modem sets the +FIS parameter from the +FCC parameter on initialization,
	when +FCC is written, and at the end of a session.

Class 2	+FDIS=
Write Syntax:	+FCC=VR,BR,WD,LN,DF,EC,BF,ST
Values:	See Table 3.5
Default:	1,3,2,2,0,0,0,0
	The Class 2 parameter is essentially the same as the Class 2.1 parameter except
	that it lacks the JP subparameter, and the +FDIS parameter is set from the +FDCC
	parameter.
Current Session Results
Class 2.1	+FCS?
Read syntax:	+FCS?
Response:	VR,BR,WD,LN,DF,EC,BF,ST,JP
Values:	See Table 3.5
Default:	0,0,0,0,0,0,0,0,0
	The +FCS parameter is loaded with the negotiated T.30 parameters for the current
	session. A transmitting modem generates DCS; a receiving modem gets DCS from
	the remote station. The host may only read this parameter.
	The +FCS parameter is set to 0,0,0,0,0,0,0,0 on initialization, on +FIP command
	execution, and at the beginning of a session. If the host issues a +FCS? command in
	the initial state, the modem will report: <CR><LF>0,0,0,0,0,0,0,0<CR><LF>
	The contents of +FCS are spontaneously reported during execution of +FDR (2.3.5)
	or +FDT (2.3.3) commands by the +FCS:VR,BR,WD,LN,DF,EC,BF,ST,JP response,
	using the same compound parameter format. See T.30 Phase B Negotiation
	Responses section.
Class 2	+FDCS?
Read syntax:	+FDCS?
Response:	+FDCS=VR,BR,WD,LN,DF,EC,BF,ST or: +FDCS=
Values:	See Table 3.5
Default:	0,0,0,0,0,0,0,0
	The Class 2 parameter is essentially the same as the Class 2.1 parameter except
	that the response lacks the JP subparameter.
