Actually, you partially know that the cable is OK. The test you did
would pass with both a modem cable and a null modem cable.

Do you have a null modem cable? This is the kind that you need to
connect a PC (which is a DTE device) to the gumstix (which is also a
DTE device).

This page:

shows the wiring for both.
