procedure. Command Mode Commands

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

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
