Serial loopback

Hi all,

it's possible to create two virtual serial device wich write and read from file or a pipe?
If yes, how?

I need it for debugging purpose because my notebook has only one serial port so i can't use a null-modem.
It also impossible to use two separate thread, to read and write from the same port , due to mutual-lock problem.

Any ideas?

Thank's, Max

P.S. Sorry, english is not my language.....

In linux you can use ptys: f.ex. /dev/ptyp0 as master (must be opened first) and /dev/ttyp0 as slave.
