Using the vedirect class.

$ python vedirect.py --port /dev/vmodem1

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 or use a live recording from test/mppt.dump

$ cat test/mppt.dump > /dev/vmodem0
