Re: Gps multiplexing and raeding directly from com port

Well if you read from the real port then only one programs can read from it.
If you read from the multiplexer port, then other programs can access the
GPS device same time as you do. If your applicaiton integrates with 3rd
party navigation solutions then you would probrably want the navigation
system to also use the GPS device

For me, the most performance effective way to do this is by polling the
COM port using the native ReadFile function. You'll have to parse the
NMEA strings yourself though.

Is there any difference in reading the virtual comport or the real
comport?
I guess no.
