Thanks for your patch, it's correct and I'll apply it once I get to
a machine with CVS access (unless somebody else applies it earlier
;-) ).

Unfortunately, the problem is wider - there are several other
issues with the current OS/2 implementation (if you just quickly
compare it with e.g. the GO32v2 implementation, you'd find some
other problems too - e.g. handling of #8 is surely incorrect etc.).
The main problem is that there's a lot platform independent
functionality in Crt unit which is re-implemented for every
platform again and again. The best solution would be to throw all
the individual implementations away completely and implement
cross-platform Crt unit based on capabilities provided by units
Keyboard and Video (possibly missing functionalities within these
units necessary for Crt could be either handled by platform
specific include file, or by extending current Keyboard and/or
Video). This issue has been discussed several times in the core
team already, but nobody found the time for doing it yet due to
higher priority tasks. Would you be willing to give it a try by any
chance?

Regards

Tomas
