(or the equivalent type of logic for a network port) On the plus side, Realterm hasn't missed a beat with continuous 9600bd serial data coming through a TCP pipe. Other programs I've tried haven't been able to keep up (drop characters occasionally). I'm not concerned about 100% usage, just intrigued.
