Hello,

I'm looking for help on a problem I currently have with Monitoring Com ports
with Borland Builder C++. I use createprocess to open Dos programs that use
the com ports. My problem is the com port code written in C++ that monitors
the serial port with treads. Once I open a Dos program, and use it for
serial communication when the program is closed I can't access the com ports
anymore through Windows 98. I have to reboot the PC so Windows can use the
ports. If I remove my monitoring code I can access the com ports with Dos
and Windows. So can I use Assembly to monitor the com status without
affecting Dos and Windows. If so can someone suggest site for information on
how to do this.

Thanks for your time

Clinton
