[aprssig] Unusual terminal behaviour

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
