COMS Virtual Cable

[Marnicola]

Does anybody have any idea
how do it a virtual cable
for application that communicate
via serial interface ??

I have an existing application to program PLCs
that use a serial interface (COM1 or you can choose).
I want to develop a PLC simulation able to communicate
with the application using another (COM3).

So i want to develop a tool capable override the cable
and allow my simulator to communicate with the
existing application (COM1 <-> COM3)

Naturally in C#

Thanks

Hi

a tool capable override the cable

you have to write a Windows device driver.
But you can't develop drivers in Win32/C++ or even C#/.NET.
Only with the Windows DDK.
