Tried every null modem cable I own, as well as built a standard one (switch pin 2 to pc pin 3, pc pin 2 to switch pin 3, pin 5 to pin 5) but I cannot get any output from the console port. I am using hyper terminal with the correct com port, 9600-8-n-1 VT100 terminal emulation. How can I tell if this unit is passing through it's POST and booting properly?
