Very useful for debugging. Of course this program won't work with hardware that decodes the signals itself like e.g. TV cards or the Irman. <P> <P> smode2 uses the svgalib to show the IR waveform in a graphical representation. The time division is variable from 1 ms/unit to extremely high values (integer type) but there is no point increasing this value above 20 ms/unit, because one pulse is about 1 ms. This kind of presentation is much more exciting than the simple pulse&space output showed by mode2. <DL COMPACT> <DT><B>-h</B> <B>--help</B><DD> display usage summary <DT><B>-v</B> <B>--version</B><DD> display version <DT><B>-d</B> <B>--device</B>=<I>device</I><DD> read from given device <DT><B>-t</B> <B>--timediv</B>=<I>value</I><DD> ms per unit </DL> <A NAME="lbAE"> </A> <!-- +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ --> <BR><BR> <CENTER>[<A HREF="http://www.lirc.org/">LIRC homepage</A>]<BR> <I>The LIRC Manual, last update: 12-Sep-2002</I></CENTER> <BR><BR> </TD> <TD WIDTH="15%"> <BR></TD> </TR> </TABLE> </TD> </TR> <TR> <TD CLASS="menu" WIDTH="100%"> <BR> </TD> </TR> </TABLE> </BODY> </HTML>
