I have a basic Arduino sketch. It reads from the serial port and prints the
chars onto an LCD.
If I use the Arduino's serial monitor and start typing stuff in, it works great and displays each character to the display.
However, I'm trying to use this library to write to the port: https://github.com/voodootikigod/node-serialport
When I try to write to the port, I can see the tx light flashing but nothing appears on the screen at all.
Is there a way to spy on the data being sent down the wire to do what is different between the 2 cases? I apologise for my bad terminology.
