         I would suggest you connect the TNC to a computer and see if 
you can read the strings from it.  If not, then you know the data 
isn't getting to the TNC and there is something else going on.  If 
the TNC doesn't have the strings in it, try putting a null modem 
between the GPS and TNC and see if that fixes it.
