1401 ** This comment is a little out of context here, but it contains
1402 ** some useful information...
1403 ********************************************************************
1404 **
1405 ** The following lines take care of the Logitech MouseMan protocols.
1406 **
1407 ** NOTE: There are different versions of both MouseMan and TrackMan!
1408 ** Hence I add another protocol P_LOGIMAN, which the user can
1409 ** specify as MouseMan in his XF86Config file. This entry was
1410 ** formerly handled as a special case of P_MS. However, people
1411 ** who don't have the middle button problem, can still specify
1412 ** Microsoft and use P_MS.
1413 **
1414 ** By default, these mice should use a 3 byte Microsoft protocol
1415 ** plus a 4th byte for the middle button. However, the mouse might
1416 ** have switched to a different protocol before we use it, so I send
1417 ** the proper sequence just in case.
1418 **
1419 ** NOTE: - all commands to (at least the European) MouseMan have to
1420 ** be sent at 1200 Baud.
1421 ** - each command starts with a '*'.
1422 ** - whenever the MouseMan receives a '*', it will switch back
1423 ** to 1200 Baud. Hence I have to select the desired protocol
1424 ** first, then select the baud rate.
1425 **
1426 ** The protocols supported by the (European) MouseMan are:
1427 ** - 5 byte packed binary protocol, as with the Mouse Systems
1428 ** mouse. Selected by sequence "*U".
1429 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1430 ** by sequence "*V".
1431 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1432 ** Selected by sequence "*X".
1433 **
1434 ** The following baud rates are supported:
1435 ** - 1200 Baud (default). Selected by sequence "*n".
1436 ** - 9600 Baud. Selected by sequence "*q".
1437 **
1438 ** Selecting a sample rate is no longer supported with the MouseMan!
1439 ** Some additional lines in xf86Config.c take care of ill configured
1440 ** baud rates and sample rates. (The user will get an error.)
