More than likely, its the wrong cable. I ran into a similar problem getting an old managed switch to work. (had a mini-din=8 serial console).
the pin outs are different on the switch were different than mac serial. Ie, pin 1 is used on the switch console port while pin 2 is doing nothing. On macs, pin 1 does nothing and pin 2 is used. There were other horrible mismatches. The only real option it to go to blackbox.com and get a couple of mini din 8 to din 9 serial adaptors then use a null modem cable. be prepared to hack the cable as necessary to get the pinouts correct.
