2.7 INITIALIZING THE CPU MEMORY
If the battery in the CPU has been changed there will be nonsense characters
in the twenty stored patterns and in certain other memory areas. To clear the memory,
send the command C, followed by ENTER to one of the serial ports.
2.8 SETTING A DIFFERENT BAUD RATE
All the communication ports on the Chameleon256 are set at the factory for
9600 baud, no parity, 1 or 2 stop bits. To change a baud rate, send the command U
followed by a two-digit number followed by an ENTER. The first digit in the string
is the port, 1 to 4, and the second is the speed:
1
1200 baud
2
2400 baud
3
9600 baud
4
19.2Kbaud
CAUTION! -- Setting a different baud rate for one of the ports can cause a
communications failure in the event another operator is unaware of the
change. Use this command with caution.

The controller can be programmed to recall the twenty crosspoint patterns

a T followed by a one-, two-, or three-digit number corresponding to the number of
seconds between patterns, followed by an ENTER.
To stop the timed mode, send an N followed by an ENTER.
Examples: T2[ENTER], T20[ENTER], T999[ENTER]
