+FPOLL - Indicate Polling Request
Syntax +FPOLL:
This message is sent to the DTE if the received DIS message indicates that the remote
station has a document to poll (by bit 9 in the DIS) and polling has been enabled with the
AT+FSPL command. The DTE may then decide to receive rather than transmit.
Service Class 2 Parameters
All Service Class 2 parameters can be read, written, and tested for range of legal values
by the DCE. The general syntax is described earlier in this appendix.
Group 3 FAX devices negotiate session parameters in DIS, DCS, and DTC frames. The
following parameters are provided to condition the facsimile DCE for the capabilities it
will offer and to report the session settings negotiated.
The three primary T.30 session parameters are +FDCC, +FDIS, and +FDCS. They are
compound parameters, using values listed in Table A-23.
+FDCC - DCE Capabilities Parameters
Write syntax: +FDCC=VR,BR,WD,LN,DF,ED,BF,ST
Valid values: See Table A-23.
Default values: 0,3,0,2,0,0,0,0 (9600 bps fax models) or 0,5,0,2,0,0,0,0 (14400 bps fax models)
+FDCC allows the DTE to sense and constrain the capabilities of the facsimile DCE from the
choices defined in CCITT T.30 Table 2. When +FDCC is modified by the DTE, the DCE copies
+FDCC into +FDIS.
+FDIS - Current Sessions Capabilities Parameters
Write syntax: +FDIS=VR,BR,WD,LN,DF,EC,BF,ST
Valid values: See Table A-23.
Default values: 0,3,0,2,0,0,0,0 (9600 bps fax models) or 0,5,0,2,0,0,0,0 (14400 bps fax models)
The +FDIS parameter allows the DTE to sense and constrain the capabilities used for the
current session. The DCE uses +FDIS to generate DIS or DTC messages directly, and
uses +FDIS and received DIS messages to generate DCS messages.
The DCE initializes the +FDIS parameter from the +FDCC parameter on initialization,
when +FDCC is written, and at the end of a session.
+FDCS - Current Session Results Parameters
Read syntax: +FDCS?
DCE response: +FDCS=VR,BR,WD,LN,DF,EC,BF,ST
or +FDCS=
Valid values: See Table A-23.
Default values: 0,0,0,0,0,0,0,0
