37 ** Mouse daemon : listens to a serial port, the bus mouse interface, or
38 ** the PS/2 mouse port for mouse data stream, interprets data and passes
39 ** ioctls off to the console driver.
40 **
41 ** The mouse interface functions are derived closely from the mouse
42 ** handler in the XFree86 X server.  Many thanks to the XFree86 people
43 ** for their great work!

1011     ** some useful information...
1012     ********************************************************************
1013     **
1014     ** The following lines take care of the Logitech MouseMan protocols.
1015     **
1016     ** NOTE: There are different versions of both MouseMan and TrackMan!
1017     **       Hence I add another protocol P_LOGIMAN, which the user can
1018     **       specify as MouseMan in his XF86Config file. This entry was
1019     **       formerly handled as a special case of P_MS. However, people
1020     **       who don't have the middle button problem, can still specify
1021     **       Microsoft and use P_MS.
1022     **
1023     ** By default, these mice should use a 3 byte Microsoft protocol
1024     ** plus a 4th byte for the middle button. However, the mouse might
1025     ** have switched to a different protocol before we use it, so I send
1026     ** the proper sequence just in case.
1027     **
1028     ** NOTE: - all commands to (at least the European) MouseMan have to
1029     **         be sent at 1200 Baud.
1030     **       - each command starts with a '*'.
1031     **       - whenever the MouseMan receives a '*', it will switch back
1032     **	 to 1200 Baud. Hence I have to select the desired protocol
1033     **	 first, then select the baud rate.
1034     **
1035     ** The protocols supported by the (European) MouseMan are:
1036     **   -  5 byte packed binary protocol, as with the Mouse Systems
1037     **      mouse. Selected by sequence "*U".
1038     **   -  2 button 3 byte MicroSoft compatible protocol. Selected
1039     **      by sequence "*V".
1040     **   -  3 button 3+1 byte MicroSoft compatible protocol (default).
1041     **      Selected by sequence "*X".
1042     **
1043     ** The following baud rates are supported:
1044     **   -  1200 Baud (default). Selected by sequence "*n".
1045     **   -  9600 Baud. Selected by sequence "*q".
1046     **
1047     ** Selecting a sample rate is no longer supported with the MouseMan!
1048     ** Some additional lines in xf86Config.c take care of ill configured
1049     ** baud rates and sample rates. (The user will get an error.)

1264     *         are very rare, however, and we quickly gain sync again after

1266     *         we could use bit 0x08 in the header byte for resyncing, since
