Gemini GV servo driver with arduino Mega 2560 - advices needed.

Ideally: The aim is to control and drive the servo motor with a know path. The path will be a txt file, containing positions and time, and the X software to translate this to step/direction or CW/CCW signal and drive the servo driver.

For example, the txt file could be like:

time (ms) position (rev)
0 0
100 200
200 300
300 150
400 -150
500 -550

I thought I would use arduino as an output mostly and a toolkit to have some parameters ready (the pulse width for example).
Is the "Q Serial Terminal" difficult to be programmed? Do you believe that it could give the necessary results?
