Robertto, Another way is to drop a Microchip Pic in your com box, if you use one of the smaller 18f 40 pin versions you have heaps of analog and bidirectional digital io pins, and construction wise you only need add an xtal and an rs232 or Ethernet chip to the Pic. Power it with 5v from your pc supply if you like. Easy to breadbord with off the shelf matrix board and wire wrap wire.
You can code it in C and knock up (clone) a custom io routine to compile into FG which reads and writes direct to the property tree and talk to it on serial or network. I run my sim hardware which is all genuine gutted radios and Boeing panels etc with pics in this way. You are welcome to my source code for the FG IO and the pics. You will need to complie FG, and the pic xcompiler is windows based not linux but seems to run ok in an emulator ok.
