+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:
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:
