Well, first of all, I would try running a program like sertest to see
if your device is working properly.

Which serial port are you trying to use?

Presumably you're trying to use a console-vx board?

Which type of cable do you have? (null modem cable or straight through cable?)
For connecting to a device that plugs into the PC, I would expect that
you'd need the straight through cable. You need to use the null modem
cable when connecting from the gumstix to the PC, but normally a
straight through cable when going from the gumstix to a device.
