Our PC-compatibles "run" at 19200 also, but the actual throughput is closer to 4800 baud. They run at 19200 by using flow control. Does the ISN use xon/xoff, DTR, or some other method? Is your software on the Mac II set the same way? I've had no trouble with a Mac II at 38400 (Versaterm PRO, I think) through an Encore Annex. Robert -- Robert K.
