I read incoming data fine, the problem is with outgoing. For instance, if I type A and then type T I get TA when I type the T. Is there a way of resetting the status register so that my keyboard interrupts don't get reinterpreted? I'm just assuming that that is what's happening. Is there a way to shut off keyboard interrupts while accepting the other port 2 interrupts or do I just have to keep sorting them out? I've noticed that the problem only occurs if there is no input from the modem between the keystrokes. This should be sufficient to explain the problem but I can't make it out. Thanks in advance Bob Church CS656@OUACCVMB
