I have Red Hat Linux 7.1 running with several Comtrol Rocketport serial boards. I want to find out what baud rate they are running at.
When I type in
setserial -a /dev/ttyR1
it gives message
cannot get serial info: Invalid argument
I have tried setserial -a -multiport /dev/ttyR1 and it says unrecognized command or even will do a kernel panic.
What command do I need to give?
