Derez, Thanks for the app, I ran it and got anError ay sub timer1_tick line 88 If Serial.InBufferCount>0 then gps. .....
Error TargetInvocationEception
??
Just before that it briefly showed port 3 baud 2400 - does that sound right?
Also when the dll was copied across I cant actually see it in the directory. Do these librarys go invisible when they r on the storage card??
