5.5.3 +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 5-2.
Default values: 0,0,0,0,0,0,0,0
The +FDCS parameter is loaded with the negotiated T.30 parameters for the current session. A transmitting DCE generates
DCS; a receiving DCE gets DCS from the remote station. The DTE may read this parameter.
The +FDCS parameter is initialized 0,0,0,0,0,0,0,0 upon initialization and at the beginning of a session. If the DTE issues a
+FDCS? command in the initial state, the DCE reports:
<CR><LF>0,0,0,0,0,0,0,0<CR><LF>
The contents of +FDCS are spontaneously reported during execution of +FDR or +FDT commands by the
+FDCS:VR,BR,WD,LN,BF,EC,BF,ST response using the same compound parameter format.
Several commands and responses reference T.30 session negotiated parameters. These are described by a set of common
subparameters. These subparameters are described in Table 5-2 with notes. Optional parameter values are marked with an *.
Unspecified parameter values are reserved for future use.
The +FDCC, +FDIS, and +FDCS compound parameters use these session parameters (On writes, unspecified
subparameters are unchanged.)
The +FDIS:, +FDCS:, and +FDTC: session report responses use these subparameters.
For test response, ranges of values are reported for each subparameter enclosed in parentheses characters. For example, a
DCE response to +FDCC=? could report:
<CRLF> (0,1), (0-5), (0-3), (0-2), (0-2), (0-2), (0), (0-7) <CRLF> (14400 fax models)
Example:
+FDIS=0,5,0,2,0,0,0,1 =
VR = 0 98 dpi vertical resolution,
BR = 5 14400 bit/s
WD = 0 1728 pixels,
LN = 2 unlimited length
DF = 0 1-D modified Huffman coding,
EC = 0 no ECM,
BF = 0 no BFT,
ST = 1 5 ms scan time.
