There is nothing wring with using the Port[] array, even under OS/2.  After
all, it is just a wrapper to access I/O ports, that still goes through OS/2
protection mechanisms.  It certainly is both easier and faster than issuing
DosDevIOCtl calls.

In other words, you have never succeeded in getting VP to compile any
program for you at all?  Which version do you use?  Which error message
does it give at the "end."?

The DosDevIOCtl functions in VP and SP differ, because C header files can
be translated to a number of different Pascal headers.  SpeedSoft have
decided to pass VAR parameters instead of pointers, whereas the VP version
expects pointers instead - it produces the same code and is really comes
down to the judgment of the person converting the header files.

If you are interested, I will post you some source code doing what you
want, provided you tell me what that is :-)

Yours,
