It apparently depended on which PSK's you had (or had not) installed. In the particular case that was brought to my attention, the printer would enable DTR to single the computer that it was ready for data, and the series 400 machine would refuse to transmit because it had the definition of DTR/CTS reversed. These problems did not show up on DN3xxx/4xxx machines, only on HP/Apollo 400 series machines. -- David Krowitz krowitz@richter.mit.edu (18.83.0.109) krowitz%richter.mit.edu@eddie.mit.edu krowitz%richter.mit.edu@mitvma.bitnet (in order of decreasing preference)
