The problem is worse if the terminal driver attempts to use silo alarms rather than taking interrupts immediately upon receipt of incoming characters. Perhaps you can settle a question for me. When running such a terminal driver at 19.2 kB, how much must the terminal be able to buffer after sending the DC3? Paul
