/*
* Driver status
* 04/04/2002: Working driver
* 05/06/2002: Reading of return value
* 02/09/2002: KeyPad handling and return string
* 03/09/2002: New icon incorporated
*
* THINGS NOT DONE:
* + No checking if right hardware is connected (firmware/hardware)
* + No BigNum (but screen is too small ???)
* + No support for multiple instance (require private structure)
* + No cache of custom char usage (like in MtxOrb)
*
* THINGS DONE:
* + Stopping the live reporting (of temperature)
* + Stopping the reporting of temp and fan (is it necessary after reboot)
* + Use of library for hbar and vbar (good but library could be better)
* + Support for keypad (Using a KeyRing)
*
* THINGS TO DO:
* + Make the caching at least for heartbeat icon
* + Create and use the library (for custom char handling)
*
