Creating Virtual Serial Ports in Ubuntu

1. Install

   sudo apt-get install socat
   

2. Create two virtual serial ports
   

   $ socat -d -d pty,raw,echo=0 pty,raw,echo=0
   2012/05/31 12:41:56 socat[28162] N PTY is /dev/pts/6
   2012/05/31 12:41:56 socat[28162] N PTY is /dev/pts/7
   2012/05/31 12:41:56 socat[28162] N starting data transfer loop with FDs [3,3] and [5,5]
   

To Test, open two terminals

• Terminal 1:

  cat < /dev/pts/6
  

• Terminal 2

  echo "hello" > /dev/pts/7
  

You should see hello echo-ed on terminal 1
