1929 * 2 delayed right - right pressed, waiting for left
1930 * 3 pressed middle - right and left pressed, emulated middle sent

1932 * 5 pressed right - right pressed and sent
1933 * 6 released left - left released after emulated middle
1934 * 7 released right - right released after emulated middle
1935 * 8 repressed left - left pressed after released left
1936 * 9 repressed right - right pressed after released right
1937 * 10 pressed both - both pressed, not emulating middle
1938 *
1939 * At each state, we need handlers for the following events
1940 * 0: no buttons down
1941 * 1: left button down
1942 * 2: right button down
1943 * 3: both buttons down
1944 * 4: emulate3Timeout passed without a button change

1947 * left down to right down without anything in between, so all cases must be
1948 * handled.

1952 * 1: action2
1953 * 2: new emulation state

1955 * action > 0: ButtonPress
1956 * action = 0: nothing

2660** The following lines take care of the Logitech MouseMan protocols.
2661** The "Logitech" protocol is for the old "series 9" Logitech products.
2662** All products since then use the "MouseMan" protocol. Some models
2663** were programmable, but most (all?) of the current models are not.
2664**
2665** NOTE: There are different versions of both MouseMan and TrackMan!
2666** Hence I add another protocol PROT_LOGIMAN, which the user can
2667** specify as MouseMan in his XF86Config file. This entry was
2668** formerly handled as a special case of PROT_MS. However, people
2669** who don't have the middle button problem, can still specify
2670** Microsoft and use PROT_MS.
2671**
2672** By default, these mice should use a 3 byte Microsoft protocol
2673** plus a 4th byte for the middle button. However, the mouse might
2674** have switched to a different protocol before we use it, so I send
2675** the proper sequence just in case.
2676**
2677** NOTE: - all commands to (at least the European) MouseMan have to
2678** be sent at 1200 Baud.
2679** - each command starts with a '*'.
2680** - whenever the MouseMan receives a '*', it will switch back
2681** to 1200 Baud. Hence I have to select the desired protocol
2682** first, then select the baud rate.
2683**
2684** The protocols supported by the (European) MouseMan are:
2685** - 5 byte packed binary protocol, as with the Mouse Systems
2686** mouse. Selected by sequence "*U".
2687** - 2 button 3 byte MicroSoft compatible protocol. Selected
2688** by sequence "*V".
2689** - 3 button 3+1 byte MicroSoft compatible protocol (default).
2690** Selected by sequence "*X".
2691**
2692** The following baud rates are supported:
2693** - 1200 Baud (default). Selected by sequence "*n".
2694** - 9600 Baud. Selected by sequence "*q".
2695**
2696** Selecting a sample rate is no longer supported with the MouseMan!
