58 | * ++roman: The following changes were applied manually: | |
59 | * | |
60 | * - The Alt (= Meta) key works in combination with Shift and | |
61 | * Control, e.g. Alt+Shift+a sends Meta-A (0xc1), Alt+Control+A sends | |
62 | * Meta-Ctrl-A (0x81) ... | |
63 | * | |
64 | * - The parentheses on the keypad send '(' and ')' with all | |
65 | * modifiers (as would do e.g. keypad '+'), but they cannot be used as | |
66 | * application keys (i.e. sending Esc O c). | |
67 | * | |
68 | * - HELP and UNDO are mapped to be F21 and F24, resp, that send the | |
69 | * codes "\E[M" and "\E[P". (This is better than the old mapping to | |
70 | * F11 and F12, because these codes are on Shift+F1/2 anyway.) This | |
71 | * way, applications that allow their own keyboard mappings | |
72 | * (e.g. tcsh, X Windows) can be configured to use them in the way | |
73 | * the label suggests (providing help or undoing). | |
74 | * | |
75 | * - Console switching is done with Alt+Fx (consoles 1..10) and | |
76 | * Shift+Alt+Fx (consoles 11..20). | |
77 | * | |
78 | * - The misc. special function implemented in the kernel are mapped | |
79 | * to the following key combinations: | |
80 | * | |
81 | * ClrHome -> Home/Find | |
82 | * Shift + ClrHome -> End/Select | |
83 | * Shift + Up -> Page Up | |
84 | * Shift + Down -> Page Down | |
85 | * Alt + Help -> show system status | |
86 | * Shift + Help -> show memory info | |
87 | * Ctrl + Help -> show registers | |
88 | * Ctrl + Alt + Del -> Reboot | |
89 | * Alt + Undo -> switch to last console | |
90 | * Shift + Undo -> send interrupt | |
91 | * Alt + Insert -> stop/start output (same as ^S/^Q) | |
92 | * Alt + Up -> Scroll back console (if implemented) | |
93 | * Alt + Down -> Scroll forward console (if implemented) | |
94 | * Alt + CapsLock -> NumLock | |
95 | * | |
96 | * ++Andreas: | |
97 | * | |
98 | * - Help mapped to K_HELP | |
99 | * - Undo mapped to K_UNDO (= K_F246) | |
100 | * - Keypad Left/Right Parenthesis mapped to new K_PPAREN[LR] | |

117 | /* ++roman: If a keyboard overrun happened, we can't tell in general how much |
118 | * bytes have been lost and in which state of the packet structure we are now. | |
119 | * This usually causes keyboards bytes to be interpreted as mouse movements | |
120 | * and vice versa, which is very annoying. It seems better to throw away some | |
3ad2f3fb | 121 | * bytes (that are usually mouse bytes) than to misinterpret them. Therefore I |
c04cb856 MS |
122 | * introduced the RESYNC state for IKBD data. In this state, the bytes up to |
123 | * one that really looks like a key event (0x04..0xf2) or the start of a mouse | |
124 | * packet (0xf8..0xfb) are thrown away, but at most 2 bytes. This at least | |
125 | * speeds up the resynchronization of the event structure, even if maybe a | |
126 | * mouse movement is lost. However, nothing is perfect. For bytes 0x01..0x03, | |
127 | * it's really hard to decide whether they're mouse or keyboard bytes. Since | |
128 | * overruns usually occur when moving the Atari mouse rapidly, they're seen as | |
129 | * mouse bytes here. If this is wrong, only a make code of the keyboard gets | |
25985edc | 130 | * lost, which isn't too bad. Losing a break code would be disastrous, |
c04cb856 MS |
131 | * because then the keyboard repeat strikes... |
