Quatech makes a Serial Port Manager, a box with serial ports on it, that connects to a host via TCP/IP. Quatech doesn’t provide a QNX driver, but I happen to have one now, in case anyone is interested.
Lately, I bought a Quatech PCMCIA Serial card (dual ports). So far no luck to make it work. Any ideas? I am running QNX 4.25 with latest patches. The machine is IBM Thinkpad T43.
You might have to modify the PCMCIA config files. What does “pin” say?
