Description Gerald Teschl 2000-12-26 11:13:56 EST
I have an ASUS laptop with an (internal) winbond controller. Works fine
under 7.0.

I installed irda-utils and changed DEVICE in /etc/sysconfig/irda to point
to ttyS1.

Starting irda results in:

Comment 1 Bernhard Rosenkraenzer 2000-12-27 12:09:19 EST
This is a kernel problem. Reassigning.
Comment 2 Glen Foster 2001-01-11 16:05:45 EST
This defect is considered MUST-FIX for Florence Gold release
Comment 3 Michael K. Johnson 2001-01-19 14:35:20 EST
IRDA currently doesn't function right without debugging
turned on.  We'll either turn debugging on or (more likely)
fix the problem the right way.
Comment 4 Michael K. Johnson 2001-01-19 14:55:03 EST
Fixed in our current sources.  Thanks!
