There does not appear to be a way to get any external "output" status
sent from the program. The only external "input" directives must use
simulated keyboard presses, and the functions they control must be on
the key mapping page. But commercial operators take note... How do
you disable the coin/currency acceptors when the jukebox is "sleeping"
("Lock Juke")? Apparently you can't unless you provide some custom
hardware to intercept the keystroke you defined and use it to control
the activation of the acceptors. Same goes for marquee lights... You
would want those dark as well when the jukebox is paused. One possible
way (which I guess does not exist, or is published anywhere) is to
use the keyboard indicator LED's (e.g. Num Lock, Scroll Lock, etc.)
as status outputs. Most i-PAC boards apparently can be configured
to activate output pins according to the keyboard indicator function.
Just a thought... Tkx...
