3 # Virtual Serial Port API Example
7 echo "You must specify your virtual serialport. (/dev/ttyACM0 on linux, /dev/cu.usbmodemXXXX on OSX)"
8 echo " ex: $0 /dev/ttyACM0"
11 # XXX Set this to match your virtual serialport
12 # TODO Show example for Cygwin/Windows
13 # For Mac OSX it will be something like /dev/cu.usbmodem1413 (number may differ)
16 # NOTE: Make sure you don't write too quickly to the serial port, it can get overwhelmed by a modern computer
17 # Generally this just means commands will get ignored
18 # I'm using 100 ms sleeps here, but much smaller are probably sufficient
