1621 ** The following lines take care of the Logitech MouseMan protocols.
1623 ** NOTE: There are different versions of both MouseMan and TrackMan!
1624 ** Hence I add another protocol P_LOGIMAN, which the user can
1625 ** specify as MouseMan in his XF86Config file. This entry was
1626 ** formerly handled as a special case of P_MS. However, people
1627 ** who don't have the middle button problem, can still specify
1628 ** Microsoft and use P_MS.
1630 ** By default, these mice should use a 3 byte Microsoft protocol
1631 ** plus a 4th byte for the middle button. However, the mouse might
1632 ** have switched to a different protocol before we use it, so I send
1633 ** the proper sequence just in case.
1635 ** NOTE: - all commands to (at least the European) MouseMan have to
1636 ** be sent at 1200 Baud.
1637 ** - each command starts with a '*'.
1638 ** - whenever the MouseMan receives a '*', it will switch back
1639 ** to 1200 Baud. Hence I have to select the desired protocol
1640 ** first, then select the baud rate.
1642 ** The protocols supported by the (European) MouseMan are:
1643 ** - 5 byte packed binary protocol, as with the Mouse Systems
1644 ** mouse. Selected by sequence "*U".
1645 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1646 ** by sequence "*V".
1647 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1648 ** Selected by sequence "*X".
1650 ** The following baud rates are supported:
1651 ** - 1200 Baud (default). Selected by sequence "*n".
1652 ** - 9600 Baud. Selected by sequence "*q".
1654 ** Selecting a sample rate is no longer supported with the MouseMan!
1655 ** Some additional lines in xf86Config.c take care of ill configured
1656 ** baud rates and sample rates. (The user will get an error.)
