12.25 AT+FTH Transmit Data Using HDLC Framing
The AT+FTH command causes the TA to transmit data using the HDLC protocol and the modulation schemes
defined in Section 12.1, FAX parameters. An ERROR response code results if the command is issued while the
modem is on-hook. The test command can be used in off-hook mode to check the modulation schemes sup-
ported by MC55.
