Posted by Morseman on Jan. 08 2003,5:44 pmLately I've been getting more and more problems with incomplete downloads. Usually Tracks, which end with a 'Buffer Overrun' error when I try to do a download from the GPSr.
Sometimes, restarting the download cures the problem, at other times it does not.
I use my GPSIII+ with a TH-D7E (Hand held rig with built in TNC for APRS) but even if I go out without connecting the H/H the problem seems to occur.

Gary (Gimpy) may have a better answer for you as he has one also and keeps in the "Know"

I've never seen this before, Morseman. I've been running the III Plus since March, 2001, & it has never given me an error of any kind. Unit has been rock solid since the day I got it. Couldn't begin to guess what's causing it.

Well, it was good advice, but only up to a point. I now have an updated version of MapSource, so I can load some files that I'd not been able to in the past.
I've also confirmed that the firmware in my GPSIII+ is the latest one anyway.
However, the Buffer Overrun problem still continues.
It seems to happen with both the Track uploads from the GPSr and the map downloads to the GPSr.
I'm wondering if it's because I use a switch to select either the GPSr or the telephone modem? I wonder if this might cause problems, anyone had experience of putting a switch in the line between PC and GPSr? I'll do a test or two and see what happens...
Posted by PC Medic on Jan. 14 2003,7:30 pmBeing a computer tech, I am going to bet that the switch is a very good suspect. I see this all the time with external CD drives and printers connected via hubs and switch boxes.
It certainly is worth a shot to try it without the switch-box.
