You will have to contact Computone for the driver download specs, and probably programming information. Depending on how old your Xenix is, the driver operates by DMAing chunks of 24 or 32 characters at a time into the Xenix clist structs, and this will probably have to change drastically for 386BSD/NetBSD (it had to change for Xenix as well, since the 32 bytes was older Xenix implementations and using old drivers with the new clist struct size would crash Xenix flat if you got burst I/O of more than 24 characters). I kind of doubt computone will give out the interface information or the programming information for the on-board 80186 (especially if it's not an ATvantage but an Atvantage/X), but you can always try.
