1933 * 2 delayed right - right pressed, waiting for left
1934 * 3 pressed middle - right and left pressed, emulated middle sent

1936 * 5 pressed right - right pressed and sent
1937 * 6 released left - left released after emulated middle
1938 * 7 released right - right released after emulated middle
1939 * 8 repressed left - left pressed after released left
1940 * 9 repressed right - right pressed after released right
1941 * 10 pressed both - both pressed, not emulating middle
1942 *
1943 * At each state, we need handlers for the following events
1944 * 0: no buttons down
1945 * 1: left button down
1946 * 2: right button down
1947 * 3: both buttons down
1948 * 4: emulate3Timeout passed without a button change

1951 * left down to right down without anything in between, so all cases must be
1952 * handled.

1960 * action = 0: nothing

2664** The following lines take care of the Logitech MouseMan protocols.
2665** The "Logitech" protocol is for the old "series 9" Logitech products.
2666** All products since then use the "MouseMan" protocol. Some models
2667** were programmable, but most (all?) of the current models are not.
2668**
2669** NOTE: There are different versions of both MouseMan and TrackMan!
2670** Hence I add another protocol PROT_LOGIMAN, which the user can
2671** specify as MouseMan in his XF86Config file. This entry was
2672** formerly handled as a special case of PROT_MS. However, people
2673** who don't have the middle button problem, can still specify
2674** Microsoft and use PROT_MS.
2675**
2676** By default, these mice should use a 3 byte Microsoft protocol
2677** plus a 4th byte for the middle button. However, the mouse might
2678** have switched to a different protocol before we use it, so I send
2679** the proper sequence just in case.
2680**
2681** NOTE: - all commands to (at least the European) MouseMan have to
2682** be sent at 1200 Baud.
2683** - each command starts with a '*'.
2684** - whenever the MouseMan receives a '*', it will switch back
2685** to 1200 Baud. Hence I have to select the desired protocol
2686** first, then select the baud rate.
2687**
2688** The protocols supported by the (European) MouseMan are:
2689** - 5 byte packed binary protocol, as with the Mouse Systems
2690** mouse. Selected by sequence "*U".
2691** - 2 button 3 byte MicroSoft compatible protocol. Selected
2692** by sequence "*V".
2693** - 3 button 3+1 byte MicroSoft compatible protocol (default).
2694** Selected by sequence "*X".
2695**
2696** The following baud rates are supported:
2697** - 1200 Baud (default). Selected by sequence "*n".
2698** - 9600 Baud. Selected by sequence "*q".
2699**
2700** Selecting a sample rate is no longer supported with the MouseMan!
