s Rockwell Semiconductor Zodiac Serial Protocol
Coded from official protocol specs (Order No. GPS-25, 09/24/1996, Revision 11)
Maintainer: Bob Ippolito
The following Rockwell Zodiac messages are currently understood::
EARTHA\r\n (a hack to "turn on" a DeLorme Earthmate)
1000 (Geodesic Position Status Output)
1002 (Channel Summary)
1003 (Visible Satellites)
1011 (Receiver ID)
The following Rockwell Zodiac messages require implementation::
None really, the others aren't quite so useful and require bidirectional communication w/ the device
Other desired features::
- Compatability with the DeLorme Tripmate and other devices with this chipset (?)
