Re: Controlling MDrive 23 ( schneider elect ) with Python....
ser = serial.Serial('/dev/ttyUSB0', 19200) Does your firmware really ask for just 19200 baud? More typical are 115200 or even 250000 baud. 250000 baud don't work so well on Linux, though.

The default baud rate is 9600.

you guys ROCK ! Thanks for clarifying my ignorance....can't wait to try. I tried 19200 and 4800 for baud rates and figured that they should work since those two values are mentioned on the MDrive data...
