Writing or reading directly to hardware is dangerous under Windows because
you can't be sure what other apps are doing.  Therefore, you should either:
1.  Go thru the Windows API for comm functions (our PSS people will be happy
to explain this ... actually quite easy)
2.  Use a custom control available from several vendor such as MicroHelp
and Crescent (among others)

>Are they available in the new Visual Basic for DOS?
Yes.  Every last language feature that Basic PDS has, incl. INP and OUT
work unmodified in VB/DOS.  Please keep in mind that VB/DOS has the Basic
PDS 7.1 code at its core...we didn't try to emulate QB/PDS, we built on top
of it .. like we did for VB/Win.

>Does Visual Basic for DOS have routines for programming mouse interaction?
Absolutely.  Forms and controls work automatically with a mouse.  You do not
write one byte of code for it.

>Will Quickbasic 4.5 *.QLB & *.LIB libraries work with VB for DOS?
Generally yes but you should call your vendor.  The libs need to work
with Far Strings (virtual all commercial .libs/.qlbs already do).  Your
vendor might also have enhanced versions of your current libs.
