Chapter 3 – Fax Class 2 Commands

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

Null String

 

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

Write syntax:

+FPI=”<local polling ID string>”

Values:

20-character printable ASCII string

Mandatory Values: 20-character string, Table 3/T.30

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.

Values:

20-character printable ASCII string
