Motorola G24 Guide Developer's Manual page 513

After the entering active session mode (G24 sent CONNECT to the terminal), the terminal can
perform one of the following:
•
If the terminal sends additional data, the G24 transmits another frame
•
If the terminal sends only <DLE><ETX> (a null frame), the G24 turns off the transmit
carrier and sends the CONNECT result code to the terminal
•
If five seconds elapses from the time the G24 reports the OK result code without any
additional data transmitted from the terminal, the G24 turns off the transmit carrier, returns to
command mode, and sends the ERROR result code to the terminal.

CONNECT 19200
(Terminal sends TSI frame data, as described in ITU-T30 with terminating sequence)
CONNECT 19200 //The G24 detected the terminating sequence
(Terminal sends DCS frame data, as described in ITU-T30 with terminating sequence and drops the
carrier)
OK

Syntax
FTH = <MOD>
(Send data stream
<DLE><ETX>)
MOD = 3 (Clause 2/V.21) rate 300 bps, is mandatory.
If the G24 detects a carrier after the FTH command, it sends a CONNECT to the terminal.
If not, it sends "NO CARRIER".
