A.2.3 Communications Baud Rate
The normal communication speed between the PC and the CSM1 is 19200
baud. However, when CSMCOM first starts it performs a simple test on the
speed of access to the serial port. If access is slow, as happens with older IBM
PC computers, the baud rate is reduced to 9600.
Some recent high-performance computers will reliably support serial
communications at speeds higher than 19200 baud. For such computers, the
speed of offloading data from the CSM1 can be increased by manually setting
the baud rate to 38400 baud.
You can set the baud rate at which CSMCOM initially tries to communicate by
specifying the baud rate, followed by 'B', as the command line parameter that
follows NOCOLOR/SM232A (if used). Valid baud rates are 300, 600, 1200,
2400, 4800, 9600, 19200, and 38400. In common with the DOS MODE
command, you do not have to specify the trailing zeros, i.e. 12B is equivalent
to 1200B.
Examples:
csmcom 384B
csmcom SM232A 9600B
CSMCOM has the same capability as GRAPHTERM and
SMCOM to send character strings, with wait periods. Please
refer to the PC208 manual. NOTE
