Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+ * Building an adaptor to DE9 / DB25 RS232
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * DISCLAIMER: Use this description AT YOUR OWN RISK! I'll not pay for
+ * anything if you break your mouse, your computer or whatever!
+ *
+ * In theory, this mouse is a simple RS232 device. In practice, it has got
+ * a quite uncommon plug and the requirement to additionally get a power
+ * supply at +5V and -12V.
+ *
+ * If you look at the socket/jack (_not_ at the plug), we use this pin
+ * numbering:
+ *    _______
+ *   / 7 6 5 \
+ *  | 4 --- 3 |
+ *   \  2 1  /
+ *    -------
+ *
+ *	DEC socket	DE9	DB25	Note
+ *	1 (GND)		5	7	-
+ *	2 (RxD)		2	3	-
+ *	3 (TxD)		3	2	-
+ *	4 (-12V)	-	-	Somewhere from the PSU. At ATX, it's
+ *					the thin blue wire at pin 12 of the
+ *					ATX power connector. Only required for
+ *					VSXXX-AA/-GA mice.
+ *	5 (+5V)		-	-	PSU (red wires of ATX power connector
+ *					on pin 4, 6, 19 or 20) or HDD power
+ *					connector (also red wire).
+ *	6 (+12V)	-	-	HDD power connector, yellow wire. Only
+ *					required for VSXXX-AB digitizer.
+ *	7 (dev. avail.)	-	-	The mouse shorts this one to pin 1.
+ *					This way, the host computer can detect
+ *					the mouse. To use it with the adaptor,
+ *					simply don't connect this pin.
+ *
+ * So to get a working adaptor, you need to connect the mouse with three
+ * wires to a RS232 port and two or three additional wires for +5V, +12V and
+ * -12V to the PSU.
+ *
+ * Flow specification for the link is 4800, 8o1.
+ *
+ * The mice and tablet are described in "VCB02 Video Subsystem - Technical
+ * Manual", DEC EK-104AA-TM-001. You'll find it at MANX, a search engine
+ * specific for DEC documentation. Try
+ * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1
