1945 * 2 delayed right - right pressed, waiting for left
1946 * 3 pressed middle - right and left pressed, emulated middle sent

1948 * 5 pressed right - right pressed and sent
1949 * 6 released left - left released after emulated middle
1950 * 7 released right - right released after emulated middle
1951 * 8 repressed left - left pressed after released left
1952 * 9 repressed right - right pressed after released right
1953 * 10 pressed both - both pressed, not emulating middle

1956 * 0: no buttons down
1957 * 1: left button down
1958 * 2: right button down
1959 * 3: both buttons down
1960 * 4: emulate3Timeout passed without a button change

2676** The following lines take care of the Logitech MouseMan protocols.
2677** The "Logitech" protocol is for the old "series 9" Logitech products.
2678** All products since then use the "MouseMan" protocol. Some models
2679** were programmable, but most (all?) of the current models are not.
2680**
2681** NOTE: There are different versions of both MouseMan and TrackMan!
2682** Hence I add another protocol PROT_LOGIMAN, which the user can
2683** specify as MouseMan in his XF86Config file. This entry was
2684** formerly handled as a special case of PROT_MS. However, people
2685** who don't have the middle button problem, can still specify
2686** Microsoft and use PROT_MS.
2687**
2688** By default, these mice should use a 3 byte Microsoft protocol
2689** plus a 4th byte for the middle button. However, the mouse might
2690** have switched to a different protocol before we use it, so I send
2691** the proper sequence just in case.
2692**
2693** NOTE: - all commands to (at least the European) MouseMan have to
2694** be sent at 1200 Baud.
2695** - each command starts with a '*'.
2696** - whenever the MouseMan receives a '*', it will switch back
2697** to 1200 Baud. Hence I have to select the desired protocol
2698** first, then select the baud rate.
2699**
2700** The protocols supported by the (European) MouseMan are:
2701** - 5 byte packed binary protocol, as with the Mouse Systems
2702** mouse. Selected by sequence "*U".
2703** - 2 button 3 byte MicroSoft compatible protocol. Selected
2704** by sequence "*V".
2705** - 3 button 3+1 byte MicroSoft compatible protocol (default).
2706** Selected by sequence "*X".
2707**
2708** The following baud rates are supported:
2709** - 1200 Baud (default). Selected by sequence "*n".
2710** - 9600 Baud. Selected by sequence "*q".
2711**
2712** Selecting a sample rate is no longer supported with the MouseMan!
