Chapter 3 – Fax Class 2 Commands

Report Remote ID

Class 2.1

+FTI:, +FCI:, +FPI:

Syntax:

+FTI:”<TSI ID string>” Transmit Station ID

Syntax:

+FCI:”<CSI ID string>” Called Station ID

Syntax:

+FPI:”<CIG ID string>” Polling Station ID

 

These responses report the received remote ID string, if any. They are generated in

 

execution of the Originate, Answer, +FDT, and +FDR commands.

 

The modem reports the characters in the ID string in reversed time order from the

 

order received from the remote station. For example, if the following ID FIF character

 

string were received (hexadecimal values):

 

<20><20><20><20><20><31><30><39><38><20><37><36><35><20><34><33>

 

<32><20><31><2B>

 

The result would be:

 

<CR><LF>+FCI:"+1 234 567 8901 "<CR><LF>

Class 2

+FTSI:, +FCSI:, +FCIG:

Syntax:

+FTSI:”<TSI ID string>” Transmit Station ID

Syntax:

+FCSI:”<CSI ID string>” Called Station ID

Syntax:

+FCIG:”<CIG ID string>” Polling Station ID

 

The Class 2 responses are essentially the same as the Class 2.1 responses.

Report Non-Standard Negotiation Frames

Class 2.1

+FNF:, +FNS:, +FNC:

Syntax:

+FNF:<NSF FIF string> Non-Standard Facilities

Syntax:

+FNS:<NSS FIF string> Non-Standard Setup

Syntax:

+FNC:<NSC FIF string> Non-Standard Commands

 

These responses report received non-standard negotiation frames, one response per

 

frame. These responses are generated in execution of the Originate, Answer, +FDT,

 

and +FDR commands.

 

The NSF Facsimile Information Field (FIF) frame octets are presented in hex

 

notation, and are separated by spaces. Flags and zero bits are removed. Frame octets

 

are reported in the order received. For each frame octet the LSB is the first bit sent or

 

received.

Class 2

+FNSF:, +FNSS:, +FNSC:

Syntax:

+FNSF:<NSF FIF string>

Non-Standard Facilities

Syntax:

+FNSS:<NSS FIF string>

Non-Standard Setup

Syntax:

+FNSC:<NSC FIF string>

Non-Standard Commands

The Class 2 responses are essentially the same as the Class 2.1 responses.
