/**
|
|
** This comment is a little out of context here, but it contains
|
|
** some useful information...
|
|
********************************************************************
|
|
**
|
|
** The following lines take care of the Logitech MouseMan protocols.
|
|
**
|
|
** NOTE: There are different versions of both MouseMan and TrackMan!
|
|
** Hence I add another protocol P_LOGIMAN, which the user can
|
|
** specify as MouseMan in his XF86Config file. This entry was
|
|
** formerly handled as a special case of P_MS. However, people
|
|
** who don't have the middle button problem, can still specify
|
|
** Microsoft and use P_MS.
|
|
**
|
|
** By default, these mice should use a 3 byte Microsoft protocol
|
|
** plus a 4th byte for the middle button. However, the mouse might
|
|
** have switched to a different protocol before we use it, so I send
|
|
** the proper sequence just in case.
|
|
**
|
|
** NOTE: - all commands to (at least the European) MouseMan have to
|
|
** be sent at 1200 Baud.
|
|
** - each command starts with a '*'.
|
|
** - whenever the MouseMan receives a '*', it will switch back
|
|
** to 1200 Baud. Hence I have to select the desired protocol
|
|
** first, then select the baud rate.
|
|
**
|
|
** The protocols supported by the (European) MouseMan are:
|
|
** - 5 byte packed binary protocol, as with the Mouse Systems
|
|
** mouse. Selected by sequence "*U".
|
|
** - 2 button 3 byte MicroSoft compatible protocol. Selected
|
|
** by sequence "*V".
|
|
** - 3 button 3+1 byte MicroSoft compatible protocol (default).
|
|
** Selected by sequence "*X".
|
|
**
|
|
** The following baud rates are supported:
|
|
** - 1200 Baud (default). Selected by sequence "*n".
|
|
** - 9600 Baud. Selected by sequence "*q".
|
|
**
|
|
** Selecting a sample rate is no longer supported with the MouseMan!
|
|
** Some additional lines in xf86Config.c take care of ill configured
|
|
** baud rates and sample rates. (The user will get an error.)
