- Added support for Genius Kidspad tablet.

# `moused' is getting too over-loaded now.  If we want something
# more than simple mouse emulation for tablets or remote devices,
# we should start writing a separate daemon...

+ * 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,
