You made some interesting points and I'll keep your post for future reference in case I ever start having problems. But for now, I use it daily without serial errors, so it appears my hack has produced no ill effects. I'm not recommending it as the *best* solution for sharing IRQs. As I stated in another thread, http://www.byterunner.com sells a variety of multiport comm boards already designed for interrupt sharing, at surprisingly reasonable cost. They have an 8-port board with 16650s for about $150, a bargain price compared to an 8-port Digiboard. I'm planning to buy several of them. It may be quicker than soldering all those diodes. :) John
