Chapter 3 – Fax Class 2 Commands
Multi-Tech Systems, Inc. SocketModem MT5634SMIxx Reference Guide (S000263C) 77
Local ID String
Class 2.1 +FLI
Write syntax: +FLI=”<local ID string>”
Values: 20-character printable ASCII string
Mandatory values: 20-character string, Table 3/T.30
Default: Null String
The modem generates a TSI or CSI frame if FLI is not a Null String. Table 3/T.30
includes digits 0–9, the + character, and the space character.
The modem transmits ID string characters to the remote station in reversed time
order from the order in the command line. For example, if the command line
AT+FLI="+1 234 567 8901"<CR> is issued, the modem would send a CSI or TSI
rame with FIF (hexadecimal) consisting of
<20><20><20><20><20><31><30><39><38><20><37><36><35><20><34>
<33><32><20><31><2B>
If less than 20 characters are specified in a non-Null String, the modem appends
space characters (<20>). If the specified string is more than 20 characters in
length, an ERROR result code is generated.
Class 2 +FLID
Write syntax: +FLID=”<local ID string>”
Valid values: 20-character printable ASCII string
Mandatory values: 20-character string, Table 3/T.30
Default value: Null String
The Class 2 parameter is essentially the same as the Class 2.1 parameter.
Local Polling ID String
Class 2.1 +FPI
Write syntax: +FPI=”<local polling ID string>”
Values: 20-character printable ASCII string
Mandatory Values: 20-character string, Table 3/T.30
Default: Null String
The modem generates a CIG frame if FPI is not a Null String. CIG is used in
polling sessions. Table 3/T.30 includes digits 0–9, the + character, and the space
character.
Like the +FLID command, the modem transmits ID string characters to the
remote station in reversed order from the order in the command line.
Class 2 +FCIG
Write syntax: +FCIG=”<local ID string>”
Values: 20-character printable ASCII string
Mandatory Values: 20-character string, Table 3/T.30
Default: Null String
The Class 2 parameter is essentially the same as the Class 2.1 parameter.
