   Change History
 
+    Wed Feb 19 22:00:00 PST 2003 (Jeffrey S. Laing <keyspan@jsl.com>)
+      Merged the current (1/31/03) Keyspan code with the current (2.4.21-pre4)
+      Linux source tree.  The Linux tree lacked support for the 49WLC and
+      others.  The Keyspan patches didn't work with the current kernel.
+
+    2003jan30	LPM	add support for the 49WLC and MPR
+
+    Wed Apr 25 12:00:00 PST 2002 (Keyspan)
+      Started with Hugh Blemings' code dated Jan 17, 2002.  All adapters
+      now supported (including QI and QW).  Modified port open, port
+      close, and send setup() logic to fix various data and endpoint
+      synchronization bugs and device LED status bugs.  Changed keyspan_
+      write_room() to accurately return transmit buffer availability.
+      Changed forwardingLength from 1 to 16 for all adapters.

+    Fri Oct 12 16:45:00 EST 2001
+      Preliminary USA-19QI and USA-28 support (both test OK for me, YMMV)
