I have Garmin's MapSource Topo 3.0 and Maptech's Terrain Navigator 5.03 both installed under CrossoverOffice 5.0.1 Pro, running on Fedora Core 4; I have been unable to install Topo.com 2.6.1, and had an intermediate result from trying Delorme TopoUSA 4.0 -- sometimes it *seems* to install, but won't open, or opens only to a plain tan screen ruled into parts, each labelled "No controls specified." Sometimes the install fails entirely. (The same also happens on TopoUSA 3.0 and on the same supplier's 3-D Topo Quads, btw & fwiw.) The two that do install open all right, and seem to do things internal to themselves normally ; but they don't manage to connect either to a Garmin Etrex Vista or to a Garmin Rino 120. Following suggestions from the CXO list, I have made sure my user btth is a member of the uucp group on that machine, and also that I see [root@localhost dev]# ls -lL ttyS* crw-rw-rw- 1 root uucp 4, 64 Feb 25 13:02 ttyS0 crw-rw-rw- 1 root uucp 4, 65 Feb 25 13:02 ttyS1 crw-rw-rw- 1 root uucp 4, 66 Feb 14 13:57 ttyS2 crw-rw-rw- 1 root uucp 4, 67 Feb 14 13:57 ttyS3 [root@localhost dev]# but the GPSs still don't connect. The same GPSs, with the same cables, do connect to the same software (including the ones that CXO doesn't handle) on a machine running XPPro/SP2, and do exchange data; so I doubt the problem is hardware. (One of my machines has a short pin in its only serial port; but I don't see anything wrong with any of the others.)
