I had a problem in that I needed three seperate feeds for
GPS on my
laptop to provide data for different programmes . I started off with two seperate inputs, (Chart +
AIS ) but then wanted to feed another programme as well (planning) .
I have located a piece of
software that takes a
single GPS feed, then creates virtual
serial ports. If you configure the different programmes to different virtual
ports, they all
work simultaneously.
