Adding custom peripherals to your computer via the serial port Answered
I built a switch for my serial port based on the lirc IR receiver design
I tested it with the program winLIRC. It is designed for recording IR signals, so all it does is measure the numbers of pulses and spaces. When I tap the switch I can see the according pulses and spaces on the screen, so I know it works.
I'm wondering how I can add this switch as an extra key. Press when I press it a window minimizes, an icon flashes, it inserts the letter 'k', or just something.
Are that programs that I can use to monitor all action on COM1?

RTS = pin 7
