I have a simple test program that attempts to open
a printer port via the following:

    fopen("lpt1", "w");

(Actually, don't pay any attention to the mode, I've tried
 every single combination listed under the fopen call).

This is from a Microsoft C 6.0 program running in a DOS
window under OS/2.

The program can never successfully open the printer - it
always gets "permission denied".

I was under the impression, (from reading the redbooks) that
OS/2 allowed the printer ports to be opened but through
various intercepts redirected printer output from a DOS box
to the Spooler. Is this not the case?

This is really bugging me, because I worked up this simple
example from a rather complex program which actually manages
to open the printer in one configuration of the program but not
in others, and I don't see, given the above, how it could do
that (the actual OS/2 printer, spooler, etc are not being
changed between program runs).

Any ideas, suggestions or solutions would be greatly appreciated.
