I am running Ubuntu 12.04.2 LTS on a PC with no serial ports. I have a Qt application that needs to connect to a serial device. I have written a simulator for this device as well.

I need a way of emulating or simulating a serial port for these two applications to communicate - they are both running on the same PC, for now.

On Windows, I used VSPE to simulate the serial port, and that works fine.

I have searched for something similar on Linux. I found:

  • Socat - I have no idea how to set it up for my scenario
  • Komport - does not seem to be what I need
  • MaxiCom - cannot get it compiled and installed

Is there a way to set up Socat for me to use, or another application to achieve the same result? It need not be free.

I never heard of the programs your talking about. At least i found tty0tty that worked great for me, but i didn't have to link two programs, just wanted to simulate a nullmodem cable between to serial ports.
