Command:  +FDCS  Current Session Results Parameters 

Description: 

 

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.  

 

 

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) 

Read syntax: +FDCS? 
DCE response:   

+FDCS=VR,BR,WD,LN,DF,EC,BF,ST 

  

or 

 

  

+FDCS= 

Valid values:    

See Table 3-2. 

Default values:   

0,0,0,0,0,0,0,0 

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. 

 

 

Command:  +FLID=  Local ID String 

Description: 

 

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) (32-127)<CRLF>.” The first “(20)” represents string length: 
the second (character values) field reports supported string values. 

  

1. 

The string is saved in RAM. 

  

2. 

Non-numeric characters are not filtered out. 

  

3. 

The string is right justified. 

Write syntax:    

+FLID="<local ID string>" 

Valid value:  

 

20-character ASCII string 

Default value:    

Empty
