Chapter 6 – Fax Class 1 and Class 1.0 Commands

Reporting Current or Selected Values: Command: +FTM? Response: +FTM: <mod>

Example: +FTM: 98 For V.17 9600 bps.

Reporting Supported Range of Parameter Values: Command: +FTM=?

Response: +FTM: (<mod> range)

Example: +FTM: 3,24,48,72,73,74,96,97,98,121,122,145,146

Command: +FRM

Receive Facsimile

Description:

This command causes the modem to enter the receiver mode using the

 

modulation defined below.

Defined Values:

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

 

data rates shown in Table 6-2.

Reporting Current or Selected Values:

 

Command: +FRM?

 

Response: +FRM: <mod>

 

Example: +FRM: 98 For V.17 9600 bps.

Reporting Supported Range of Parameter Values:

 

Command: +FRM=?

 

Response: +FRM: (<mod> range)

 

Example: +FRM: 3,24,48,72,73,74,96,97,98,121,122,145,146

Result Codes:

CONNECT Reported when the selected carrier is detected.

 

+FCERROR Reported if another carrier is detected and FAR=0; the modem

 

then returns to the command state.

 

NO CARRIER Reported if loss-of-carrier is detected.

 

OK Reported if the DTE sends any character to the modem other than XON or

 

XOFF while operating in configured flow control from the DTE; the modem

 

then returns to the command state.

Command: FTH

Transmit Data with HDLC Framing

Description:

This command causes the modem to transmit data using HDLC protocol and

 

the modulation defined below.

Defined Values:

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

 

data rates shown in Table 6-2.

Result Codes:

CONNECT Reported for either of two conditions:

 

1. At the beginning of transmission of the training pattern for the selected

 

modulation.

 

2. If the Final Frame bit is 0.

 

OK Reported for either of two conditions:

 

1. If the Final Frame Bit is 1.

 

2. if the DTE sends only <DLE><ETX> (a null frame) while transmitting flags.

 

ERROR Reported if five seconds elapse from the time when the modem

 

reported the CONNECT result code without any additional data transmitted

 

from the DTE; the modem then turns off carrier and returns to the command

mode.

Reporting Current or Selected Values: Command: +FTH? Response: +FTH: <mod>

Example: +FTH: 98 For V.17 9600 bps.

Reporting Supported Range of Parameter Values: Command: +FTH? Response: +FTH?

Example: +FTH: 98 For V.17 9600 bps.
