Great point Dave. If a line printer was fitted with a DB9 connector would it actually exist?

If I understand your question correctly, no, I've never seen nor heard of a large printer with a DE9 connector. However, lots and lots of them have RS232 serial ports, but on standard DB25 connectors. That's how LSSM's big Genicom is interfaced; it's connected to a DECserver terminal server so that multiple systems can access it. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
