I have been using Nobeltec
VNS v4.1.347 on an older Toshiba laptop
for a number of years with XP. Two months ago it operated normally, that is, announcing that it could not find port COM1 but connecting with COM9 and functioning OK.
A month ago it gave the same opening announcement BUT there was no GPS
come up OK but no navigation
due to no GPS
input. GPS data is provided by a Garmin
GPS 76 or GPSMAP 76 via USB-RS232 converter. As this is a dedicated navigation
computer, it was only connected to the Internet
for monthly Microsoft updates; that is once between working and not working before the problem started.
I have uninstalled then reinstalled both the USB to RS232
cable converter and also Nobeltec software
without any improvement except that now it doesn't make the previous announcement for not finding COM1, an improvement I would think. The XP Device Manager shows no problem with either the Ports
or the Universal Serial
Bus Controllers but is now reflecting COM8 for the USB-RS232 which I have now selected in Nobeltec Input Ports
Everything seems to be what it should be but I still have no GPS input from Garmin
. I'm frustrated and open to suggestions.
