I have something running on the /dev/ttyp0 of my PC? How can i connect to this port?

It's not a port, it's a pseudoterminal. If you have sufficient privileges you can read.write the /dev/ttyp0. Saying what exactly you're running and what you're trying to do would be of great help in giving a more useful answer than this.

I have started Qemu OS emulator. I tried to read it with "cat< /dev/ttypX", but that didn't give me any output.

From where did you start qemu? The one and only time I ever played with it, I just typed qemu into a terminal and it popped up a little window on the screen and ran. Did yours not do this?

Sorry, i didn't mention everything:
- I logged in my debian amd64 server via ssh
- I chrooted to the ia-32 environment
- I started qemu with the "-nographic" option
and started playing with these options:

Code:

`-serial dev'
    Redirect the virtual serial port to host device dev. Available devices are:

    vc
        Virtual console 
    pty
        [Linux only] Pseudo TTY (a new PTY is automatically allocated) 
    null
        void device 
    stdio
        [Unix only] standard input/output 

    The default device is vc in graphical mode and stdio in non graphical mode. This option can be used several times to simulate up to 4 serials ports.

Look into minicom, that should do exactly what you want
