I used to work at a law office that had an AT&T Starserver. It had two "concentrators" that each could attach to two 12 port (IIRC) serial "hubs". The serial lines went to terminals and printers, and used RJ-45's with TP wiring.

Those hubs are the only time _I've_ seen RJ-45 used for serial communication. -- --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- (203) 432-0953 --- ICQ # - 905818 Mac OS X 10.1 - Darwin Kernel Version 5 Running since 01/22/2002 without a crash
