Known problems
The list of known problems (on 20 November 2001) is:
- GPSMan relies on the use of a serial port to communicate with
the GPS receiver. Some Tcl/Tk installations (e.g., in SuSe and Red Hat
Linux), operating system drivers and even hardware (in some laptops)
were reported not to work correctly with the serial port. In what
concerns Tcl/Tk, upgrading to a newer version solved the problem in
most cases. To help debugging input from a serial port a Tcl/Tk
program is available from the WWW page.
It must be edited before use to set the correct path to the serial port.
- GPSMan releases 5.3 and later cannot be run under
Tcl/Tk 8.0 due to bugs in the latter. The recommended version of
Tcl/Tk is 8.3 or later.
- in older Tcl/Tk versions, neither map
background images
nor waypoint symbols
are saved to Postscript along the
other map information. Upgrading to a more recent Tcl/Tk is highly
recommended.
- due to limitations imposed by Tcl/Tk, that does not
implement communication with serial ports on Macintosh
platforms, GPSMan
will not be able to dialog with the GPS receiver on these
systems.
