I have been given a pair of Mitsubishi 4 port serial cards. These cards
appear to pretty much dumb - 4 uarts some buffer chips and a PAL. They
are full length cards and I guess fairly old. Having done the obvious
things - scanned for UART chips in the entire I/O space etc, I've got
nowhere. All I know is that they had Xenix drivers (and in this case
switching to Xenix to get the 8 ports working is out... we need NFS
and the current budget is about 15 pounds (about 25$)).
Did anyone have such a card, does anyone know where I can get info on
it - especially the programming info so I can write a Linux driver for it.
Replies by email please.
