# Arduino Monitor V0.1 for Stefan's tinybasic.

# This is a very basic serial monitor with a few special features.
# it connects to the Arduino serial port and interacts with
# Stefan's Tinybasic. 
#
# Special commands
# <cntrl> L loads a program into the Arduino - literally typing it in
# <cntrl> S saves a program from the Arduino - collects the output of LIST 
#         to save type <cntrl S>, enter the file name and then type list
#         end save mode with another <cntrl S>, then hand edit the output 
#         file to remove the "list" and "Ready"
# <cntrl> D ends the monitor 
# 
# Set the port here
