1633 ** The following lines take care of the Logitech MouseMan protocols.
1635 ** NOTE: There are different versions of both MouseMan and TrackMan!
1636 ** Hence I add another protocol P_LOGIMAN, which the user can
1637 ** specify as MouseMan in his XF86Config file. This entry was
1638 ** formerly handled as a special case of P_MS. However, people
1639 ** who don't have the middle button problem, can still specify
1640 ** Microsoft and use P_MS.
1642 ** By default, these mice should use a 3 byte Microsoft protocol
1643 ** plus a 4th byte for the middle button. However, the mouse might
1644 ** have switched to a different protocol before we use it, so I send
1645 ** the proper sequence just in case.
1647 ** NOTE: - all commands to (at least the European) MouseMan have to
1648 ** be sent at 1200 Baud.
1649 ** - each command starts with a '*'.
1650 ** - whenever the MouseMan receives a '*', it will switch back
1651 ** to 1200 Baud. Hence I have to select the desired protocol
1652 ** first, then select the baud rate.
1654 ** The protocols supported by the (European) MouseMan are:
1655 ** - 5 byte packed binary protocol, as with the Mouse Systems
1656 ** mouse. Selected by sequence "*U".
1657 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1658 ** by sequence "*V".
1659 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1660 ** Selected by sequence "*X".
1662 ** The following baud rates are supported:
1663 ** - 1200 Baud (default). Selected by sequence "*n".
1664 ** - 9600 Baud. Selected by sequence "*q".
1666 ** Selecting a sample rate is no longer supported with the MouseMan!
1667 ** Some additional lines in xf86Config.c take care of ill configured
1668 ** baud rates and sample rates. (The user will get an error.)
