Hi,

Our DOS application is able to accurately check the serial POS printer
status by checking the individual bits of that COM port from the bios.

However, under Windows, I not able to do that.
Even using the OPOS driver, I can't get my
application to work with the OPOS driver on my
printer. Due to a lack of COM port on my system,
we are testing some device that allow us to
had virtual COM port.

Anyone had any good recommend or solution to my problem.
