While searched for solution for one "serial" task (winXP) i found very nice software
This software splitter creates many virtual serial ports and redirects them to one real serial port. Before i see this one, i was thinking that only way to do this is WindowsDriverKit.
Now i'm in doubt - Xport is very compact and very easy to install . Behavior is (in my eyes) as of regular user application.
I read as many as found on Microsoft site and now i'm thinking(maybe wrong) that "serial.sys" and "serenum.sys" are drivers, trough which one can create virtual serial port. I didnt found any answer about-
-is this possible from user application?
-if yes, what library will be needed?
-if yes, is this possible with non-Microsoft compiler/library?
