/**
** 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.)

/*
* code to read from the Genius Kidspad tablet.
The tablet responds to the COM PnP protocol 1.0 with EISA-ID KYE0005,
and to pre-pnp probes (RTS toggle) with 'T' (tablet ?)
9600, 8 bit, parity odd.
The tablet puts out 5 bytes. b0 (mask 0xb8, value 0xb8) contains
the proximity, tip and button info:
(byte0 & 0x1) true = tip pressed
(byte0 & 0x2) true = button pressed
(byte0 & 0x40) false = pen in proximity of tablet.
The next 4 bytes are used for coordinates xl, xh, yl, yh (7 bits valid).
Only absolute coordinates are returned, so we use the following approach:
we store the last coordinates sent when the pen went out of the tablet,
