33.3.11 +iBDRM — Define A Fixed Baud Rate on iChip Modem Connection<br />

Syntax: <strong>AT+i</strong>BDRM=<br />

Sets the baud rate on modem connection. This parameter is<br />

saved to nonvolatile memory and activated after every powerup.<br />

Parameters: 3..9|‗a‘|‗h‘<br />

Command Options:<br />

n=a set baud rate to Auto Baud<br />

n=3 set baud rate to 2400<br />

n=4 set baud rate to 4800<br />

n=5 set baud rate to 9600<br />

n=6 set baud rate to 19200<br />

n=7 set baud rate to 38400<br />

n=8 set baud rate to 57600<br />

n=h set baud rate to 230400<br />

Default: ‗a‘ (auto baud)<br />

The iChip modem connection will be set to the same baud<br />

rate as that detected on the host iChip connection.<br />

Result Code:<br />

I/OK If n is within limits. The iChip will continue operating in the<br />

current baud rate setting. Further power-up will initialize the<br />

baud rate to the new selected value, until a different<br />

<strong>AT+i</strong>BDRM command is issued.<br />

I/ERROR Otherwise<br />

<strong>AT+i</strong>BDRM? Returns the code for the specified fixed modem baud rate<br />

followed by I/OK.<br />
