Does anyone out there know what port and interrupt com3 and com4 are using on the Telebit trailblazer. I need it to attempt to add it as a third com port to ESIX and regain one of my built in com ports. Any telebit engineers read this newsgroup? Thanks in advance. -- Jim Chandler asuvax!xroads!beagle!chandler chandler at beagle.UUCP
