The device at the other end is an Arduino Mega connected via USB and a pushbutton connected to the arduino. On the computer side is the Perl Program....I can send a command 1 or 2 and it will change LEDS on the arduino....if the button connected to the arduino is pressed it should post: Button Pressed on the serial terminal window on the computer end. It does not...it does however if the enter button is pressed it displays Button Pressed.
