Raw Blame History

/*--------------------------------------------------------------
This is a driver for the newer Astrium == Dornier chopper
systems which use a TCP/IP server for communication.
This driver has to take care of some ugliness:
- As of december 2005, the communication is in unicode!
To go from ASCII to unicode and back one has to
add a 0x00 before each character or to remove it.
- The controller is slow in responding and the controller
must be watched in the environment monitor. This is taken
care of by a special SICS task which updates the status
regularly and returning cached values anytime else.
Inititial Implementation: Mark Koennecke, December 2005
