I have proven it is HyperTerminal doing it
I used another terminal package and it works 100%
For some reason hyperterm is sending 00- when I send 000 from a file
Really odd.
Hooked up the GPS all is ok

Howdy,
NMEA Parse. looking at the field after the ",N,"
Wonder is someone has seen this before ? Using hyperterminal,
I send this
$GPVTG,300,T,001,M,000.0,N,0A01.E,K*7E and I get this out "SPD 0A01"
I send this
$GPVTG,300,T,001,M,000.0,N,0001.E,K*7E and I get this out "SPD 00-1"
It is almost as if hyperterminal is seeing any two consecutive zeros after
the ,N, and following with a "-"
Is this a particular ASCII case ? Hook it up to the GPS and all is fine.
Maybe I should try another terminal package ?
Cheers Andy vk4tec
