+ * Revision 1.6  2004/07/29 22:57:09  bernie
+ * ser_drain(): New function; Make Serial::is_open a debug-only feature; Switch to new-style CONFIG_* macros.

+ * Revision 1.5  2004/07/18 21:54:23  bernie
+ * Add ATmega8 support.

+ * Add dual-license information.
+ *
  * Revision 1.3  2004/06/02 21:35:24  aleph
  * Serial enhancements: interruptible receive handler and 8 bit serial status for AVR; remove volatile attribute to FIFOBuffer, useless for new fifobuf routens
