Of course you'll need a special cable (as if there were such a thing as a standard RS-232 cable). Use the pinouts found in macTEP, but swap pins 2 & 3 on the DB-25 side. You might also have to connect pin 2 (+5v) on the DB-9 to pin 6 (Data Set Ready) on the DB-25. As in all cases when connecting two devices for the first time, be prepared to experiment. Michael Ward, NCAR/SCD **************** I haven't found it necessary to alter the pin connections. The same cable works fine. Maybe it is a question of selecting the right "Communication" parameters out of the "Settings" menu in MacTerminal. Use "Other Computer" rather than "Modem". -- Martin Taylor {allegra,linus,ihnp4,floyd,ubc-vision}!utzoo!dciem!mmt {uw-beaver,qucis,watmath}!utcsrgv!dciem!mmt
