12.6 AT+FTH Transmit Data Using HDLC Framing
The AT+FTH command causes the TA to transmit data using the HDLC protocol and the modulation scheme
<mod>=3.
An ERROR response code results if the write command is issued while the modem is on-hook. The test com-
mand can be used either in on-hook or off-hook mode to check the value supported by the <mod> parameter.
