1964 * 1 delayed left - left pressed, waiting for right
1965 * 2 delayed right - right pressed, waiting for left
1966 * 3 pressed middle - right and left pressed, emulated middle sent
1967 * 4 pressed left - left pressed and sent
1968 * 5 pressed right - right pressed and sent
1969 * 6 released left - left released after emulated middle
1970 * 7 released right - right released after emulated middle
1971 * 8 repressed left - left pressed after released left
1972 * 9 repressed right - right pressed after released right
1973 * 10 pressed both - both pressed, not emulating middle
1974 *
1975 * At each state, we need handlers for the following events
1976 * 0: no buttons down
1977 * 1: left button down
1978 * 2: right button down
1979 * 3: both buttons down
1980 * 4: emulate3Timeout passed without a button change

1982 * pressed now. It's possible (ie, mouse hardware does it) to go from (eg)
1983 * left down to right down without anything in between, so all cases must be
1984 * handled.

1987 * 0: action1
1988 * 1: action2
1989 * 2: new emulation state
1990 *
1991 * action > 0: ButtonPress
1992 * action = 0: nothing
1993 * action < 0: ButtonRelease

2699** The following lines take care of the Logitech MouseMan protocols.
2700** The "Logitech" protocol is for the old "series 9" Logitech products.
2701** All products since then use the "MouseMan" protocol. Some models
2702** were programmable, but most (all?) of the current models are not.
2703**
2704** NOTE: There are different versions of both MouseMan and TrackMan!
2705** Hence I add another protocol PROT_LOGIMAN, which the user can
2706** specify as MouseMan in his XF86Config file. This entry was
2707** formerly handled as a special case of PROT_MS. However, people
2708** who don't have the middle button problem, can still specify
2709** Microsoft and use PROT_MS.
2710**
2711** By default, these mice should use a 3 byte Microsoft protocol
2712** plus a 4th byte for the middle button. However, the mouse might
2713** have switched to a different protocol before we use it, so I send
2714** the proper sequence just in case.
2715**
2716** NOTE: - all commands to (at least the European) MouseMan have to
2717** be sent at 1200 Baud.
2718** - each command starts with a '*'.
2719** - whenever the MouseMan receives a '*', it will switch back
2720** to 1200 Baud. Hence I have to select the desired protocol
2721** first, then select the baud rate.
2722**
2723** The protocols supported by the (European) MouseMan are:
2724** - 5 byte packed binary protocol, as with the Mouse Systems
2725** mouse. Selected by sequence "*U".
2726** - 2 button 3 byte MicroSoft compatible protocol. Selected
2727** by sequence "*V".
2728** - 3 button 3+1 byte MicroSoft compatible protocol (default).
2729** Selected by sequence "*X".
2730**
2731** The following baud rates are supported:
2732** - 1200 Baud (default). Selected by sequence "*n".
2733** - 9600 Baud. Selected by sequence "*q".
2734**
2735** Selecting a sample rate is no longer supported with the MouseMan!
