Yes - I've built two interfaces for my Paragon - One using a transistor, 
the other using an optocoupler. Both work equally well (I drive them 
through a COM port using a MOXA expansion card that gives me 4 
additional COM ports) for me using MMTTY. I found schematics for both 
designs on internet web pages. I prefer the optocoupler design due to 
the isolation it provides. I can dig back through my notes to see if the 
web pages are still available, if you would like.
