AT
Silence AFTER Sequence - Sets period of silence after the
command sequence characters in mS.
Range:0 – 1000
(mS)
500
BD
Baud Rate – Sets serial com port baud rate (bps). Over-the-
air (throughput) baud rate is set with ATR2 command.
If a PC’s serial baud rate is set higher than the fixed over-the-
air baud rate of the module, hardware handshaking may be
required.
Range: 0 – 6
0 = 1200 bps
1 = 2400
2 = 4800
3 = 9600
4 = 19200
5 = 38400
6 = 57600

the command sequence character in mS.
Range: 0-1000
mS
500
CH
Configure Hardware Flow Control – Enable (1) or disable
(0) flow control. When enabled, the modem will monitor the
RTS line, and if it is negated, stop sending data out the serial

the Command Mode only.
Range: 0 , 1
0 (no
echo)
F
Display frequencies – Display all of the frequencies
programmed into all of the channel memories.

FT
Transmit Frequency – Program the transmit frequency for
this channel. Enter in Hz or in MHz. The frequency will
automatically be saved in non-volatile memory (flash) for this
current channel number.
Range: See product data sheet.
