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.
