1620 ** The following lines take care of the Logitech MouseMan protocols.
1622 ** NOTE: There are different versions of both MouseMan and TrackMan!
1623 ** Hence I add another protocol P_LOGIMAN, which the user can
1624 ** specify as MouseMan in his XF86Config file. This entry was
1625 ** formerly handled as a special case of P_MS. However, people
1626 ** who don't have the middle button problem, can still specify
1627 ** Microsoft and use P_MS.
1629 ** By default, these mice should use a 3 byte Microsoft protocol
1630 ** plus a 4th byte for the middle button. However, the mouse might
1631 ** have switched to a different protocol before we use it, so I send
1632 ** the proper sequence just in case.
1634 ** NOTE: - all commands to (at least the European) MouseMan have to
1635 ** be sent at 1200 Baud.
1636 ** - each command starts with a '*'.
1637 ** - whenever the MouseMan receives a '*', it will switch back
1638 ** to 1200 Baud. Hence I have to select the desired protocol
1639 ** first, then select the baud rate.
1641 ** The protocols supported by the (European) MouseMan are:
1642 ** - 5 byte packed binary protocol, as with the Mouse Systems
1643 ** mouse. Selected by sequence "*U".
1644 ** - 2 button 3 byte MicroSoft compatible protocol. Selected
1645 ** by sequence "*V".
1646 ** - 3 button 3+1 byte MicroSoft compatible protocol (default).
1647 ** Selected by sequence "*X".
1649 ** The following baud rates are supported:
1650 ** - 1200 Baud (default). Selected by sequence "*n".
1651 ** - 9600 Baud. Selected by sequence "*q".
1653 ** Selecting a sample rate is no longer supported with the MouseMan!
1654 ** Some additional lines in xf86Config.c take care of ill configured
1655 ** baud rates and sample rates. (The user will get an error.)
