Serial Port Configuration
Change Baud Rate <CTRL+A>I Baud Bits Parity <ENTER>
The Change Baud Rate command can be used to change the
communication parameters of any serial data port. Any changes in these
settings take effect immediately; you will need to begin using the new
settings to continue using the port after entering this command.
 Baud sets the new baud rate for the port. Supported rates are 1200,
2400, 4800, and 9600.
 Bits sets the number of data bits. Choose either 7 or 8.
 Parity sets the parity bit. Choose either o for odd, e for even, or n
for none.
Data Port Pin Assignments
Serial ports 1 and 2 use 9-pin DB9 connectors with the following pin
assignments:
These ports can be connected directly to a standard PC serial port with a
9-pin, three wire straight serial cable. A “null modem” cable MAY NOT
be used for this purpose since it will reverse the connections of pins 2
and 3.
