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 – 7
0 = 1200 5= 38400
1 = 2400 6=57600
2 = 4800 7=115200

Enable
(1) or disable
(0) flow control. When enabled, the modem will monitor the
