Followups set, hesitantly, to gmane.linux.redhat.fedora.general I thought I had posted this to both these groups, but my newsreader doesn't show it in either. I have three Garmin GPSs (an Etrex Vista and two Rino 120s), which I want to use under Fedora 11 Linux with four PCs, and two IBM- reconditioned Thinkpads, T30 & T42. Garmin software suites (Metroguide USA and Topo US 2008) are installed on all the computers; both of them launch and run under Wine on all six. Both of them also connect, consistently, to the GPSs from the PCs. *Sometimes* they also connect to the GPSs from the laptops -- and sometimes nothing I can think of makes the transfers work (or the laptops even see the GPSs, for that matter). (I'm not just misremembering. There are many waypoints, as well as a few routes and tracks, on the laptops now, which have to have come from the GPSs.) The cables I have, bought new from Garmin, all require a serial port on the computer end. The PCs have such a port, as does the T30; for the T42 I have something that calls itself a "Cardbus to Serial Port Adapter," which uses a little 10" cable with an ethernet plug on one end for the card, and a male serial plug on the other, which accepts the Garmin cables. My guess is that there is something funny in either the F11 install or the Wine install on the laptops, since all the GPSs and cables work well in at least some places. Can anyone suggest a way to find the problem?? -- Beartooth Staffwright, Neo-Redneck Not Quite Clueless Power User I have precious (very precious!) little idea where up is.
