Subject: 16-Bit Device Driver + OS/2 V2.0
Newsgroups: comp.os.os2.programmer

It is my understanding and experience that if you have a 16-bit device driver
that uses 'documented interfaces', e.g. DevHelp calls, it should work on
V2.0 without modification.  I can't speak for the EZtape driver never having
used it, but perhaps it does something 'funny';  there's some device drivers
I know of that work for 1.2 and 1.3 that do some funny things with GDTs and
such that won't work with V2.0 because the 'undocumented assumptions' they made
are no longer true for V2.

To turn this around a little, if you know of a device driver that does not
work with V2 and it uses strictly documented interfaces, please let your
IBM rep know about it; we consider it a HIGH priority for these types of
things to work in V2.  If you can isolate what the problem is report it here
and I'll make sure it gets to the right people.
