Hi, i need a list of commands in the serial.sys.

I am hoping to find a way to react on a serial input.
Something like OnCom(), but entirelie build from standard system files.

As a followup, but i could start a new thread on that, i will need multitasking and windowsmessage WM_ infos.

to sum all up:
1) serial.sys reference / where to get
2) multitasking / how to do
3) Windows messages /where to get and how to do

Thanks a lot, Johannes
