1234 ** This comment is a little out of context here, but it contains
1235 ** some useful information...
1236 ********************************************************************
1237 **
1238 ** The following lines take care of the Logitech MouseMan protocols.
1239 **
1240 ** NOTE: There are different versions of both MouseMan and TrackMan!
1241 ** Hence I add another protocol P_LOGIMAN, which the user can
1242 ** specify as MouseMan in his XF86Config file. This entry was
1243 ** formerly handled as a special case of P_MS. However, people
1244 ** who don't have the middle button problem, can still specify
1245 ** Microsoft and use P_MS.
1246 **
1247 ** By default, these mice should use a 3 byte Microsoft protocol
1248 ** plus a 4th byte for the middle button. However, the mouse might
1249 ** have switched to a different protocol before we use it, so I send
1250 ** the proper sequence just in case.
1251 **
1252 ** NOTE: - all commands to (at least the European) MouseMan have to
1253 ** be sent at 1200 Baud.
1254 ** - each command starts with a '*'.
1255 ** - whenever the MouseMan receives a '*', it will switch back
1256 ** to 1200 Baud. Hence I have to select the desired protocol
1257 ** first, then select the baud rate.
1258 **
1259 ** The protocols supported by the (European) MouseMan are:
1260 ** - 5 byte packed binary protocol, as with the Mouse Systems
1261 ** mouse. Selected by sequence "*U".
1262 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1263 ** by sequence "*V".
1264 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1265 ** Selected by sequence "*X".
1266 **
1267 ** The following baud rates are supported:
1268 ** - 1200 Baud (default). Selected by sequence "*n".
1269 ** - 9600 Baud. Selected by sequence "*q".
1270 **
1271 ** Selecting a sample rate is no longer supported with the MouseMan!
1272 ** Some additional lines in xf86Config.c take care of ill configured
1273 ** baud rates and sample rates. (The user will get an error.)
