Reprap motherboard communication-ascii or unicode?

HI all,

I am writing a custom processing sketch to control the reprap motherboard with the mendel firmware on it . Could somebody please tell me whether the serial communication is ascii or is it unicode and where i can read up more about this.

I made a processing sketch which prints out the gcode as a string to the serial port, but the motherboard does not seem to be doing anything after receiving the commands.

If I use the arduino serial terminal to send the gcode commands the machine does not do anything but if i use the osx serial terminal (screen) the machine is correctly interpreting the gcode and executing it. What could be the problem here?
Is it related to ascii or unicode serial communication? Please help.

Thanks in advance,
Varun

It's ASCII, but the difference is the Arduino serial monitor doesn't send CR/LF characters at the end of the line. Add those in and you should be fine!
