Hey all,

I'm trying to design some physical Repairable Ship Components that are basically Arduino's with some kind of sensor combination.

The idea is that within the Mission Script - something causes Shields or Beam Weapons etc to loose power, a Serial message (possibly a single char) is sent to the Arduino that is the "Shield Matrix" or "Beam Weapon Control Conduits".
The Arduino then requires fixing - when this is done the Arduino sends another Serial Char that is picked up by the Mission Script and puts Shields/Beams Power back to Full..

I'm having issues getting a Mission Script to successfully send a single Char over Serial..
I have tried the following methods (for Windows) in several places in the Mission Script:

   file = io.open("COM6","wb")

   io.output(file)

   io.write("B")

^ this one seems to allow the Script to load and I can see the Mission Assets in the Game Master screen but does not send anything over Serial (Arduino is configured to light up its built-in LED upon receiving the letter "B")

and

   Arduino_Com_Port = com.open("COM6", 115200, 0)

   com.write(Arduino_Com_Port, "B")

^ this one has issues with the 'Global com not being recognized'

any help would be greatly appreciated
Thank you!
