- * Belkin is selling a dongle called the SmartBeam.

- * I guess that I've got the old one, because inside I don't have

- *
- * As far as I can make it from info on their web site, the old dongle
- * support only 9600 b/s, which make our life much simpler as far as
- * the driver is concerned, but you might not like it very much ;-)
- * The new SmartBeam does 115 kb/s, and I've not tested it...
- *
- * Belkin claim that the correct driver for the old dongle (in Windows)
- * is the generic Parallax 9500a driver, but the Linux LiteLink driver
- * fails for me (probably because Linux-IrDA doesn't rate fallback),
- * so I created this really dumb driver...
- *
- * In fact, this driver doesn't do much. The only thing it does is to
- * prevent Linux-IrDA to use any other speed than 9600 b/s ;-) This
- * driver is called "old_belkin" so that when the new SmartBeam is supported
- * its driver can be called "belkin" instead of "new_belkin".
- *
