Syntax: f1=val,f2=val [,c=on1/off1[-
on2/off2[-on3/off3]]];
(Frequencies are in Hz and cadence on
and off are in 10ms)
ON is the period of ringing ("On time" in
"ms") while OFF is the period of silence.
In order to set a continuous ring, OFF
should be zero. Otherwise, it will ring ON
ms and a pause of OFF ms and then
repeats the pattern.
