I have similar things going on. Have a cisco 2900 10/100 switch and
the machine boots up but the console port just show's me crap. But then
a minute or so the switch crashes and show's me a error message just
with no jibbrish. So I am assuming the switch itselfe is shot, and not
serial port as it has the ability to show me something usefull when it
But yes 9600/n/8/1 should do the trick. If not, good luck.
