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!

1211     ********************************************************************
1212     **
1213     ** The following lines take care of the Logitech MouseMan protocols.
1214     **
1215     ** NOTE: There are different versions of both MouseMan and TrackMan!
1216     **       Hence I add another protocol P_LOGIMAN, which the user can
1217     **       specify as MouseMan in his XF86Config file. This entry was
1218     **       formerly handled as a special case of P_MS. However, people
1219     **       who don't have the middle button problem, can still specify
1220     **       Microsoft and use P_MS.
1221     **
1222     ** By default, these mice should use a 3 byte Microsoft protocol
1223     ** plus a 4th byte for the middle button. However, the mouse might
1224     ** have switched to a different protocol before we use it, so I send
1225     ** the proper sequence just in case.
1226     **
1227     ** NOTE: - all commands to (at least the European) MouseMan have to
1228     **         be sent at 1200 Baud.
1229     **       - each command starts with a '*'.
1230     **       - whenever the MouseMan receives a '*', it will switch back
1231     **	 to 1200 Baud. Hence I have to select the desired protocol
1232     **	 first, then select the baud rate.
1233     **
1234     ** The protocols supported by the (European) MouseMan are:
1235     **   -  5 byte packed binary protocol, as with the Mouse Systems
1236     **      mouse. Selected by sequence "*U".
1237     **   -  2 button 3 byte MicroSoft compatible protocol. Selected
1238     **      by sequence "*V".
1239     **   -  3 button 3+1 byte MicroSoft compatible protocol (default).
1240     **      Selected by sequence "*X".
1241     **
1242     ** The following baud rates are supported:
1243     **   -  1200 Baud (default). Selected by sequence "*n".
1244     **   -  9600 Baud. Selected by sequence "*q".
1245     **
1246     ** Selecting a sample rate is no longer supported with the MouseMan!
1247     ** Some additional lines in xf86Config.c take care of ill configured
1248     ** baud rates and sample rates. (The user will get an error.)

1521     *         are very rare, however, and we quickly gain sync again after
1522     *         an overflow condition. This is the best we can do. (Actually,
1523     *         we could use bit 0x08 in the header byte for resyncing, since
