I'm in the process of trying to isolate why my chartplotter doesn't have a
GPS fix unless my computer's connected to the serial port my electronic
charts use.

Skip, sorry for the delay but just got home and have not been checking
USENET all that faithfully while we were underway south.

Are you saying that your chart plotter is not coming up with a GPS
position unless your computer is attached? Does it have its own GPS
antenna? Is it configured properly to use the antenna? I'd start by
totally disconnecting the computer interface and then work with
customer support as though it was a stand alone unit. It could be an
antenna problem, a cabling/connector problem or possibly a
configuration issue.
