Using the vedirect class.

$ sudo python vedirect.py

Using the vedirectsim simulator.

Create a pair of virtual serial ports which transfer data between each other.

$ socat -d -d PTY,raw,echo=0,link=/tmp/vmodem0 PTY,raw,echo=0,link=/tmp/vmodem1

Connect vedirect.py to /tmp/vmodem1 and vedirectsim.py to /tmp/vmodem0
