1220 ** This comment is a little out of context here, but it contains
1221 ** some useful information...
1222 ********************************************************************
1223 **
1224 ** The following lines take care of the Logitech MouseMan protocols.
1225 **
1226 ** NOTE: There are different versions of both MouseMan and TrackMan!
1227 ** Hence I add another protocol P_LOGIMAN, which the user can
1228 ** specify as MouseMan in his XF86Config file. This entry was
1229 ** formerly handled as a special case of P_MS. However, people
1230 ** who don't have the middle button problem, can still specify
1231 ** Microsoft and use P_MS.
1232 **
1233 ** By default, these mice should use a 3 byte Microsoft protocol
1234 ** plus a 4th byte for the middle button. However, the mouse might
1235 ** have switched to a different protocol before we use it, so I send
1236 ** the proper sequence just in case.
1237 **
1238 ** NOTE: - all commands to (at least the European) MouseMan have to
1239 ** be sent at 1200 Baud.
1240 ** - each command starts with a '*'.
1241 ** - whenever the MouseMan receives a '*', it will switch back
1242 ** to 1200 Baud. Hence I have to select the desired protocol
1243 ** first, then select the baud rate.
1244 **
1245 ** The protocols supported by the (European) MouseMan are:
1246 ** - 5 byte packed binary protocol, as with the Mouse Systems
1247 ** mouse. Selected by sequence "*U".
1248 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1249 ** by sequence "*V".
1250 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1251 ** Selected by sequence "*X".
1252 **
1253 ** The following baud rates are supported:
1254 ** - 1200 Baud (default). Selected by sequence "*n".
1255 ** - 9600 Baud. Selected by sequence "*q".
1256 **
1257 ** Selecting a sample rate is no longer supported with the MouseMan!
1258 ** Some additional lines in xf86Config.c take care of ill configured
1259 ** baud rates and sample rates. (The user will get an error.)

1531 * For resyncing a PS/2 mouse we require the two most significant
