Chapter 3 - Class 1 Fax Commands

 

 

Command:

+FRS=? <Enter>

Function:

Display the range of stop-transmission-and-wait period values

Values:

<time> = 0-255 in 10 ms intervals

Default:

0

Result Codes: the current range of values supported by the modem.

Description:

The +FRS=? command causes the modem to display the current set of stop-

 

transmission-and-wait period values supported (specified by the +FRS=<time>

 

command).

Command: +FTM=<MOD> <Enter>

Function: Transmit data with <MOD> carrier

Values: <MOD> = 3, 24, 48, 72, 73, 74, 96, 97, 98, 121, 122, 145, 146

Default: 3 (V.21 ch.2 @ 300 bps)

Result Codes: CONNECT at start of training pattern transmission; ERROR if the parameter value is out of range.

Description: The +FTM command causes the PC to transmit data using the fax modulation specified in <MOD> (see Table 3-1 for values). The modem displays the CONNECT result code, then tranmits the proper training sequence in the selected mode, followed by constant 1 bits until data is received from the PC. The modem buffers data in this mode, using the flow control method defined by the &E command. When the modem's transmit buffer is emptied, and if the last character transmitted was not a NUL, the modem turns off tranmit carrier, returns to Command mode, and displays the OK result code.

Note: The +FTM= command must be entered as the last command in the command string (i.e., it must be followed by the <Enter> key).

Command:

+FTM? <Enter>

Function:

Display the range of valid transmit data modulation values

Values:

<MOD> = 3, 24, 48, 72, 73, 74, 96, 97, 98, 121, 122, 145, 146

Default:

3 (V.21 ch.2 @ 300 bps)

Result Codes: the current value supported by the modem.

Description:

The +FTM? command causes the modem to display the current set of accepted

 

modulation for transmit data values (specified by the +FTM=<MOD> command).

Command:

+FRM =<MOD> <Enter>

Function:

Facsimile Receive with <MOD> carrier

Values:

see Table 3-1 for <MOD> (modulation) values

Default:

3 (V.21 ch.2 @ 300 bps)

Result Codes: CONNECT, NO CARRIER, or +FCERROR

Description:

The +FRM= command causes the modem to enter fax receive mode using the

 

modulation specified by <MOD> (refer to Table 3-1 for <MOD> values). The modem

 

returns to Command mode on loss of carrier, then displays the NO CARRIER result

 

code on the PC. When the modem detects the selected carrier, it sends the

 

CONNECT message. If a different signal is detected, a +FCERROR (Connect Error)

 

is displayed, and the modem returns to Command mode. The modem uses the flow

 

control method defined by the &E command. If the PC sends any character except

 

DC1 or DC3, the modem enters Command mode, and causes the PC to display the

OK result code. If this command is entered with the modem on-hook, the ERROR result code is displayed.

Note: The +FRM= command must be entered as the last command in the command string (i.e., it must be immediately followed by the <Enter> key).
