ansi bbs, 8 none one at 9600 is a good place to start.. might need a nul modem IF both ends match.. one needs to be dce, the other dte.... you can short pins 2 and 3 in the db45 to test the pc.. that allows typing on screen, but nothing else...
on a large switch, start with j25/j26 instead of the paddle boards, those talk to the ACTIVE core.. so rear of the active core NO chance of it not being default..
