812	** All products since then use the "MouseMan" protocol. Some models
813	** were programmable, but most (all?) of the current models are not.
814	**
815	** NOTE: There are different versions of both MouseMan and TrackMan!
816	** Hence I add another protocol PROT_LOGIMAN, which the user can
817	** specify as MouseMan in his XF86Config file. This entry was
818	** formerly handled as a special case of PROT_MS. However, people
819	** who don't have the middle button problem, can still specify
820	** Microsoft and use PROT_MS.
821	**
822	** By default, these mice should use a 3 byte Microsoft protocol
823	** plus a 4th byte for the middle button. However, the mouse might
824	** have switched to a different protocol before we use it, so I send
825	** the proper sequence just in case.
826	**
827	** NOTE: - all commands to (at least the European) MouseMan have to
828	** be sent at 1200 Baud.
829	** - each command starts with a '*'.
830	** - whenever the MouseMan receives a '*', it will switch back
831	** to 1200 Baud. Hence I have to select the desired protocol
832	** first, then select the baud rate.
833	**
834	** The protocols supported by the (European) MouseMan are:
835	** - 5 byte packed binary protocol, as with the Mouse Systems
836	** mouse. Selected by sequence "*U".
837	** - 2 button 3 byte MicroSoft compatible protocol. Selected
838	** by sequence "*V".
839	** - 3 button 3+1 byte MicroSoft compatible protocol (default).
840	** Selected by sequence "*X".
841	**
842	** The following baud rates are supported:
843	** - 1200 Baud (default). Selected by sequence "*n".
844	** - 9600 Baud. Selected by sequence "*q".
845	**
846	** Selecting a sample rate is no longer supported with the MouseMan!
