********************************************************************
|
|
**
|
|
** 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.)

/*
|
|
* Hack for resyncing: We check here for a package that is:
|
|
* a) illegal (detected by wrong data-package header)
|
|
* b) invalid (0x80 == -128 and that might be wrong for MouseSystems)
|
|
* c) bad header-package
|
|
*
|
|
* NOTE: b) is a voilation of the MouseSystems-Protocol, since values of
|
|
* -128 are allowed, but since they are very seldom we can easily
|
|
* use them as package-header with no button pressed.
|
|
* NOTE/2: On a PS/2 mouse any byte is valid as a data byte. Furthermore,
|
|
* 0x80 is not valid as a header byte. For a PS/2 mouse we skip
|
|
* checking data bytes.
|
|
* For resyncing a PS/2 mouse we require the two most significant
|
|
* bits in the header byte to be 0. These are the overflow bits,
|
|
* and in case of an overflow we actually lose sync. Overflows
|
|
* are very rare, however, and we quickly gain sync again after
|
|
* an overflow condition. This is the best we can do. (Actually,
|
|
* we could use bit 0x08 in the header byte for resyncing, since
|
|
* that bit is supposed to be always on, but nobody told
|
|
* Microsoft...)
