RE: self-built IR receiver with WinLIRC 0.6.5

[Russ W. <rw...@ra...>]

Hi, Johnny.

Are you using irrecord to 'learn' the signals?  Have you first tried
using the mode2 command?  This command should display a series of pulse
and space data if and only if a button is pressed on your remote
control.
