Virtual Serial Driver - Help

NTDEV
1

Hi

I want to create a Virtual serial port (say COM 5) and expose to serial
port applications. when any operations happens on this port, I want
redirect to my own PCI card driver(which can understand serial commands).

I am not interested in normal COM ports (COM1 & COM2 ) operations. I am
interested only in COM5, the port I am exposing.

Any idea how to proceed…?

I have to write this drive in Win98, Win NT and Win2K

Bye

If you have driver:works and vtoolsd they come with
serial port samples. you will need to see the interfaces
exposed. The driver::works sample comes with a base class
that can be derived to handle your virtual port requests.
There are inline comments in their code.

The driver::works sample (for NT/2K ) is based upon the ddk
serial sample.

I did a virtual serial port driver based upon this a couple months ago.

Regarding doing this in Win2k, read the section in the DDK titled “COM Port
Interfaces”
I hope this is useful.
