The modem sends information responses to the host as a facsimile session proceeds. Responses 
convey needed information and indicate the state of the facsimile session. These responses are 
solicited messages, generated in execution of host action commands described in Action Commands 
section.

 

 

The modem precedes all of the following information responses with <CR><LF>, and follow them with 
<CR><LF> if in verbose mode (ATV1) or follow them with just a <CR> if in terse mode (ATV0). 

Syntax:  

+FCO 
The +FCO response indicates connection with a Group 3 facsimile station. It is 
released by detection of HDLC flags in the first received frame. +FCO is generated in 
response to an Originate command (2.3.1) or an Answer command (2.3.2).

 

Syntax:  

 

+FCON 

The Class 2 response is essentially the same as the Class 2.1 response.

Syntax:

FDM 

The +FDM response indicates that the modem has identified that the calling device is 
a data modem. The modem issues this response immediately upon recognition of a 
data modem. The +FDM response precedes any data modem information text or 
result codes.

 

 

There is no equivalent response in Class 2.
