Hello all,

I have program, which runs correctly under win95 dpmi server,
but under clear dos v 7.0 with csdpmi5 server has strange behaviour:

The program installs protected mode driver for serial port, tries to
sends some bytes over it, but wve it also writes/reads from disk during
it, the program frees for several seconds (cca 30 secs) and then runs
agains.

The same program runs under win95 without any problems and the same
variation
of this program build by borland runs without any problems.

I am looking for some tips as I have tried several test without success.
I even created a small version of this program, but it works without any
problems
also in DOS.

So please if You have any tips, please let me know.

Best regards,
Petr Maxa
