Fax Operation

HDLC Transmit +FTH=(Mod)

+FTH=(Mod) causes the modem to transmit HDLC framed data using the modulation and speed selected with the (Mod) parameter. For V.27 ter, V.29, and V.17 modulations, the modem will first transmit the required training sequence (with echo protector tone). Configured for HDLC transmission, the modem transmits HDLC flags and returns the CONNECT result code. HDLC flags will continue to be sent until the first byte of data is received from the DTE or until 5 seconds elapses with no data. For more information, refer to the Class 1 specification.

HDLC Receive +FRH=(Mod)

The command +FRH=(Mod) causes the modem to receive HDLC framed data using the modulation and speed selected with the (Mod) parameter. If the selected carrier is detected, a CONNECT result code is sent to the DTE; if a different signal is detected, the modem sends a +FCERROR (CONNECT ERROR) result code and returns to command mode. This command will be aborted if the DTE sends any character to the modem other than DC1 or DC3 during this mode. For additional information, consult the Class 1 specification.

Test Supported Range of Values +FTx=?, +FRx=?

The supported range of values for any of the fax transmit or receive commands can be determined with the +FTx=? or +FRx=? command where x is M, H, or S. The normal transmit and receive capabilities are interrogated with +FTM=? and +FRM=?, while the HDLC transmit and receive capabilities are interrogated with +FTH=? and +FRH=?. Since the modem can send and receive normal data or HDLC data at all valid speeds up to 14,400 bps, the modem returns the information text 3, 24, 48, 72, 73, 74, 96, 97, 98, 121, 122, 145, 146 for any of these four commands if x is M or H. For the commands +FTS=? or +FRS=? the modem returns the information text 0-255, indicating an allowed time interval from 0 to 2.55 seconds. The appropriate information text is always preceded and followed by <CR><LF> and followed by an appropriate result code response.
