Bitfields for KEYBIT Lite status byte:
Bit(s)	Description	)
 7	KEYBIT Lite active
 6	E-mail support active
 5-0	reserved
Notes:	E-mail support is one of the original features of KEYBIT Lite.	It is
	  the automatic conversion of the 8-bits ASCII chars produced by some
	  keys available on Italian keyboards to couples of 7-bits chars.
	Message editors should always enable e-mail support, they should also
	  restore its original status before exiting.
	The user can change both status bits by hotkeys.
