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!

+ *
+ * TODO:
+ * -- Add true modem contol line query capability. Currently we track the
+ * states reported by the interrupt and the states we request.
+ * -- Add error reporting back to application for UART error conditions.
+ * Just point me at how to implement this and I'll do it. I've put the
+ * framework in, but haven't analyzed the "tty_flip" interface yet.
+ * -- Add support for flush commands
+ * -- Add everything that is missing :)
+ *
+ * 27-Nov-2001 gkh
+ * compressed all the differnent device entries into 1.
+ *
+ * 30-May-2001 gkh
+ * switched from using spinlock to a semaphore, which fixes lots of problems.
+ *
+ * 08-Apr-2001 gb
+ * - Identify version on module load.
+ *
+ * 12-Mar-2001 gkh
+ * - Added support for the GoHubs GO-COM232 device which is the same as the
+ * Peracom device.
+ *
+ * 06-Nov-2000 gkh
+ * - Added support for the old Belkin and Peracom devices.
+ * - Made the port able to be opened multiple times.
+ * - Added some defaults incase the line settings are things these devices
+ * can't support.
+ *
+ * 18-Oct-2000 William Greathouse
+ * Released into the wild (linux-usb-devel)
+ *
+ * 17-Oct-2000 William Greathouse
+ * Add code to recognize firmware version and set hardware flow control
+ * appropriately. Belkin states that firmware prior to 3.05 does not
+ * operate correctly in hardware handshake mode. I have verified this
+ * on firmware 2.05 -- for both RTS and DTR input flow control, the control
+ * line is not reset. The test performed by the Belkin Win* driver is
+ * to enable hardware flow control for firmware 2.06 or greater and
+ * for 1.00 or prior. I am only enabling for 2.06 or greater.
+ *
+ * 12-Oct-2000 William Greathouse
+ * First cut at supporting Belkin USB Serial Adapter F5U103
+ * I did not have a copy of the original work to support this
+ * adapter, so pardon any stupid mistakes. All of the information
+ * I am using to write this driver was acquired by using a modified
+ * UsbSnoop on Windows2000 and from examining the other USB drivers.
