Connecting NMEA Wind data from NASA Clipper

[PaddyB]

I connected the mast unit directly to hyperterminal and what i got was this:

$WIMWV,42,R
$WIMWV,42,R,
$WIMWV,41,R,

$WIMWV,346,R,3.
$WIMWV,347,R,5.
$WIMWV,354,R,1.
$WIMWV,354,R,.
$WIMWV,354,R,.
$WIMWV,354,R
$WIMWV,354,R
$WIMWV,354,R
$WIMWV,354,R

Looks like no checksum at all and only wind information when there is any wind to report - is this really NMEA? Does hyperterminal remove any checksums etc? The wind instrument reports the windspeed with one decimal but i don't see that in the messages...

Just had a look at mine in Putty - got this -
(checksum is wrong)
