- *
- * 2000/09/16 Frank Przybylski <mail@frankprzybylski.de> :
- * added timeout and relaxed pulse detection, removed gap bug
- *
- * 2000/12/15 Christoph Bartelmus <lirc@bartelmus.de> :
- * added support for Tekram Irmate 210 (sending does not work yet,
- * kind of disappointing that nobody was able to implement that
- * before),
- * major clean-up
- *
- * 2001/02/27 Christoph Bartelmus <lirc@bartelmus.de> :
- * added support for StrongARM SA1100 embedded microprocessor
- * parts cut'n'pasted from sa1100_ir.c (C) 2000 Russell King
