Parameters
Description
Remembered
This command sets the RS-232 port to a non-standard baud rate. The
command accepts a two byte parameter that goes directly into the
modules baud generator. Use the formula, speed =
calculate the [speed] for any baud rate setting. The speed can be
anywhere from 12 to 2047 which corresponds to a baud range of 977 to
153,800 baud. Setting the baud rate out of this range could cause the
display to stop working properly and require the Manual Override
jumper to be set.
