Does Processing include the ability to write Strings to serial ports? I am working on a GUI that reads from the port fine but as soon as I try to write the data 1. doesnt always actually make it to the port and execute and 2. clogs up the buffer preventing me from reading again even if I read and print what is clogging the buffer(for some reason the command I sent)  it still refuses to read from the serial port...

This is my first program in this language and I have experience with only matlab and visual basic before this so I am trying to learn... but I keep getting stuck...

Thank you in advance so much!!!
