1941 * 2 delayed right - right pressed, waiting for left
1942 * 3 pressed middle - right and left pressed, emulated middle sent

1944 * 5 pressed right - right pressed and sent
1945 * 6 released left - left released after emulated middle
1946 * 7 released right - right released after emulated middle
1947 * 8 repressed left - left pressed after released left
1948 * 9 repressed right - right pressed after released right
1949 * 10 pressed both - both pressed, not emulating middle
1950 *

1952 * 0: no buttons down
1953 * 1: left button down
1954 * 2: right button down
1955 * 3: both buttons down
1956 * 4: emulate3Timeout passed without a button change

1959 * left down to right down without anything in between, so all cases must be
1960 * handled.

1968 * action = 0: nothing

2672** The following lines take care of the Logitech MouseMan protocols.
2673** The "Logitech" protocol is for the old "series 9" Logitech products.
2674** All products since then use the "MouseMan" protocol. Some models
2675** were programmable, but most (all?) of the current models are not.
2676**
2677** NOTE: There are different versions of both MouseMan and TrackMan!
2678** Hence I add another protocol PROT_LOGIMAN, which the user can
2679** specify as MouseMan in his XF86Config file. This entry was
2680** formerly handled as a special case of PROT_MS. However, people
2681** who don't have the middle button problem, can still specify
2682** Microsoft and use PROT_MS.
2683**
2684** By default, these mice should use a 3 byte Microsoft protocol
2685** plus a 4th byte for the middle button. However, the mouse might
2686** have switched to a different protocol before we use it, so I send
2687** the proper sequence just in case.
2688**
2689** NOTE: - all commands to (at least the European) MouseMan have to
2690** be sent at 1200 Baud.
2691** - each command starts with a '*'.
2692** - whenever the MouseMan receives a '*', it will switch back
2693** to 1200 Baud. Hence I have to select the desired protocol
2694** first, then select the baud rate.
2695**
2696** The protocols supported by the (European) MouseMan are:
2697** - 5 byte packed binary protocol, as with the Mouse Systems
2698** mouse. Selected by sequence "*U".
2699** - 2 button 3 byte MicroSoft compatible protocol. Selected
2700** by sequence "*V".
2701** - 3 button 3+1 byte MicroSoft compatible protocol (default).
2702** Selected by sequence "*X".
2703**
2704** The following baud rates are supported:
2705** - 1200 Baud (default). Selected by sequence "*n".
2706** - 9600 Baud. Selected by sequence "*q".
2707**
2708** Selecting a sample rate is no longer supported with the MouseMan!
