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 A-23 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:

+FLID= - Local ID String
Write syntax:
+FLID="
Valid value:
20-character ASCII string
Default value: Empty
If FLID is not a null string, it generates a TSI or CSI frame. Table 3/T.30 includes digits
0-9, “+” and space.
If the DCE supports use of Table 3/T.30 only, the response to a +FLID=? command is
“(20) (32, 43, 48-57).” If the DCE supports printable ASCII <, the response is: “(20) (32-
