* ++roman: The following changes were applied manually:
*
* - The Alt (= Meta) key works in combination with Shift and
* Control, e.g. Alt+Shift+a sends Meta-A (0xc1), Alt+Control+A sends
* Meta-Ctrl-A (0x81) ...
*
* - The parentheses on the keypad send '(' and ')' with all
* modifiers (as would do e.g. keypad '+'), but they cannot be used as
* application keys (i.e. sending Esc O c).
*
* - HELP and UNDO are mapped to be F21 and F24, resp, that send the
* codes "\E[M" and "\E[P". (This is better than the old mapping to
* F11 and F12, because these codes are on Shift+F1/2 anyway.) This
* way, applications that allow their own keyboard mappings
* (e.g. tcsh, X Windows) can be configured to use them in the way
* the label suggests (providing help or undoing).
*
* - Console switching is done with Alt+Fx (consoles 1..10) and
* Shift+Alt+Fx (consoles 11..20).
*
* - The misc. special function implemented in the kernel are mapped
* to the following key combinations:
*
* ClrHome -> Home/Find
* Shift + ClrHome -> End/Select
* Shift + Up -> Page Up
* Shift + Down -> Page Down
* Alt + Help -> show system status
* Shift + Help -> show memory info
* Ctrl + Help -> show registers
* Ctrl + Alt + Del -> Reboot
* Alt + Undo -> switch to last console
* Shift + Undo -> send interrupt
* Alt + Insert -> stop/start output (same as ^S/^Q)
* Alt + Up -> Scroll back console (if implemented)
* Alt + Down -> Scroll forward console (if implemented)
* Alt + CapsLock -> NumLock
*
* ++Andreas:
*
* - Help mapped to K_HELP
* - Undo mapped to K_UNDO (= K_F246)
* - Keypad Left/Right Parenthesis mapped to new K_PPAREN[LR]

* introduced the RESYNC state for IKBD data. In this state, the bytes up to

* packet (0xf8..0xfb) are thrown away, but at most 2 bytes. This at least
* speeds up the resynchronization of the event structure, even if maybe a
* mouse movement is lost. However, nothing is perfect. For bytes 0x01..0x03,
* it's really hard to decide whether they're mouse or keyboard bytes. Since
* overruns usually occur when moving the Atari mouse rapidly, they're seen as
* mouse bytes here. If this is wrong, only a make code of the keyboard gets
* lost, which isn't too bad. Loosing a break code would be disastrous,
