Description Gerald Teschl 2000-12-26 16:13:56 UTC

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 17:09:19 UTC

This is a kernel problem. Reassigning.

Comment 2 Glen Foster 2001-01-11 21:05:45 UTC

This defect is considered MUST-FIX for Florence Gold release

Comment 3 Michael K. Johnson 2001-01-19 19:35:20 UTC

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 19:55:03 UTC

Fixed in our current sources.  Thanks!
