[aprssig] TNC-200 Assistance

I am quite sure that your problem is the EPROM.  TheNet is a special networking EPROM that will 
never work with UI-View.  I think that TNC is a TNC2 clone and if that is the case you need to get 
the latest software loaded into the EPROM.  If you do not have access to a prom programmer I can help.
