## Known problems

The list of known problems (on 14 June 2007) is:

1. GPSMan support for Garmin receivers may need to convert between bytes and floating point numbers. Tcl/Tk has no machine-independent way to do these conversions and GPSMan only implements them for little- or big-endian architectures that follow the IEEE floating point standard. Some Garmin receivers do not use protocols having floating point numbers and are not affected by this.
2. Tcl/Tk 8.4 conflicts with the `Img` library versions below 1.3, making it impossible to load/save images in formats other than GIF and PNM.
3. due to limitations imposed by Tcl/Tk, that does not implement communication with serial ports on some Macintosh platforms, GPSMan will not be able to dialog with the GPS receiver on these systems. See below for information on how to use a USB port under MacOS X.
