=head1 NAME
xpp_blink - Blink the leds of a specified XPD
=head1 SYNOPSIS
xpp_blink {on|off|bzzt} {span <number> | chan <number> | xpd <bus num> [<xpd num> [<lineno>]]}
=head1 DESCRIPTION
Blink all the leds of an XPD.
=head2 Blink mode:
=over
=item on
Turn on constant blink
=item off
Turn off blink
=item bzzt
Blink briefly for 1 second.
=back
=head2 Selector:
=over
=item span
Select by span number. This only work for XPD registered to dahdi.
will also print the dahdi channels of the span and the xbus/xpd this
span represents.
=item chan
Select by channel number. This only work for XPD registered to dahdi.
=item xpd
Select by xbus + xpd numbers. If only xbus number is given, all the
XPDs of the selected xbus (Astribank) are blinked.
=item label
Select by xbus label. Affect the whole Astribank.
=back
=head1 EXAMPLES
$ xpp_blink bzzt span 2
Using XBUS-04/XPD-10 (connected via usb-0000:00:1d.7-1): channels 15 16 17 18 19 20 21 22
$ xpp_blink bzzt chan 18
$ xpp_blink on xpd 0 1 5
$ xpp_blink off xpd 0
$ xpp_blink bzzt label 'usb:00000238'
