A couple of questions please George.

If special ISA Card drivers are needed I assume they won't be on the DOS start up diss, but will need to be loaded as part of the application software?

Should the echo command actually show characters RECEIVED from the RS232 port? If so I can see the possible need for RTS/CTS linking.
