Chapter 2 – Fax Class 1 and 1.0 Commands

 

 

 

 

 

 

 

 

Command:

+FRS

Receive Silence

 

 

 

Description:

 

This command causes the modem to listen and report an OK result code

 

 

 

when silence has been detected on the line for the specified period of time.

 

 

 

This command will terminate when the required period of silence is detected

 

 

 

or when the DTE sends the modem another character other than XON or

 

 

 

XOFF, which is discarded. In either event, the OK result code is returned.

 

 

 

This command is aborted if any character is received from the DTE after

 

 

 

receipt of the command but before the time delay elapses. In this case, the

 

 

 

modem discards the aborting character and issues an OK result code.

Defined Values:

 

<time> Decimal number from 0 (default) to 255 which specifies the length of

 

 

 

time in 10-ms intervals to delay before responding with the OK result code

 

 

 

after detecting silence on the line.

Result Codes:

 

OK Reported when silence has been present on the line for the specified

 

 

 

amount of time or when the DTE sends the modem a character other than

 

 

 

XON or XOFF.

 

 

 

 

 

 

ERROR <value> is invalid or this command is issued while the modem is on-

 

 

 

hook.

 

 

 

Reporting Supported Range of Parameter Values:

 

 

 

 

 

Command: +FRS=?

 

 

 

 

 

Response: +FRS: <time> range

 

 

 

 

 

Example: +FRS: 0-255

 

 

Command:

+FTM

Transmit Facsimile

 

 

Description:

 

This command causes the modem to transmit data using the modulation

 

 

 

defined below. When a valid <mod> value is entered, the modem transmits

 

 

 

the proper training sequence in the selected mode, followed by constant 1 bits

 

 

 

until data is received from the DTE. The modem also returns the CONNECT

 

 

 

result code at the beginning of the training sequence.

Defined Values:

 

<mod> Decimal number corresponding to the selected modulation mode and

 

 

 

data rates shown in Table 3-2.
