Better late than never: straight through modem cable (DB9 to DB25), 19200 baud, N,8,1, VT100 emulation. If you hit enter and don't get a password prompt, step down to 9600, then 4800, 2400, 1200, 300 to see if someone set the dipswitches wrong. If no response, your cable, serial port or software is faulty.
