Access and read to nmea sentences

[deantop]

Hello friends
I have a Montana 680 GPS device and I want to access nmea sentences from a Visual Basic program. Does anyone know how to code for it.

Thank you very much for your help.

NMEA sentences are output in readable ASCII text format, e.g. :-

GPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,130694,004.2,W*70

There is some info. on the syntax here :-
