a/d driver for venix 5

[J. C. Burgess]

Does anyone know of references about writing drivers
for a/d boards in C under unix?
Specific application is Data Translation 28xx for
IBM PC/AT using Venix V version 2.
Unisource, which sells Venix, sells a driver kit
but they want to retain ownership of anything written using it.
