Just got a Cat2100 (Grand Juncton FS2100) off eBay. It works fine if I just plug everything in, but when I connect a null-modem cable (one that worked fine with a 1516M hub) to the serial port of the 2100 and my PC, this is all I get: ATQ0H0 Any suggestions? I'd like to get into the management interface. Bill -- Bill Bradford mrbill at mrbill.net Austin, TX
