1962 * 1 delayed left - left pressed, waiting for right
1963 * 2 delayed right - right pressed, waiting for left
1964 * 3 pressed middle - right and left pressed, emulated middle sent
1965 * 4 pressed left - left pressed and sent
1966 * 5 pressed right - right pressed and sent
1967 * 6 released left - left released after emulated middle
1968 * 7 released right - right released after emulated middle
1969 * 8 repressed left - left pressed after released left
1970 * 9 repressed right - right pressed after released right
1971 * 10 pressed both - both pressed, not emulating middle
1972 *
1973 * At each state, we need handlers for the following events
1974 * 0: no buttons down
1975 * 1: left button down
1976 * 2: right button down
1977 * 3: both buttons down
1978 * 4: emulate3Timeout passed without a button change

1980 * pressed now. It's possible (ie, mouse hardware does it) to go from (eg)
1981 * left down to right down without anything in between, so all cases must be
1982 * handled.

1985 * 0: action1
1986 * 1: action2
1987 * 2: new emulation state
1988 *
1989 * action > 0: ButtonPress
1990 * action = 0: nothing
1991 * action < 0: ButtonRelease

2697** The following lines take care of the Logitech MouseMan protocols.
2698** The "Logitech" protocol is for the old "series 9" Logitech products.
2699** All products since then use the "MouseMan" protocol. Some models
2700** were programmable, but most (all?) of the current models are not.
2701**
2702** NOTE: There are different versions of both MouseMan and TrackMan!
2703** Hence I add another protocol PROT_LOGIMAN, which the user can
2704** specify as MouseMan in his XF86Config file. This entry was
2705** formerly handled as a special case of PROT_MS. However, people
2706** who don't have the middle button problem, can still specify
2707** Microsoft and use PROT_MS.
2708**
2709** By default, these mice should use a 3 byte Microsoft protocol
2710** plus a 4th byte for the middle button. However, the mouse might
2711** have switched to a different protocol before we use it, so I send
2712** the proper sequence just in case.
2713**
2714** NOTE: - all commands to (at least the European) MouseMan have to
2715** be sent at 1200 Baud.
2716** - each command starts with a '*'.
2717** - whenever the MouseMan receives a '*', it will switch back
2718** to 1200 Baud. Hence I have to select the desired protocol
2719** first, then select the baud rate.
2720**
2721** The protocols supported by the (European) MouseMan are:
2722** - 5 byte packed binary protocol, as with the Mouse Systems
2723** mouse. Selected by sequence "*U".
2724** - 2 button 3 byte MicroSoft compatible protocol. Selected
2725** by sequence "*V".
2726** - 3 button 3+1 byte MicroSoft compatible protocol (default).
2727** Selected by sequence "*X".
2728**
2729** The following baud rates are supported:
2730** - 1200 Baud (default). Selected by sequence "*n".
2731** - 9600 Baud. Selected by sequence "*q".
2732**
2733** Selecting a sample rate is no longer supported with the MouseMan!
