[arm-allstar] Auto connection if not in use

[Matthew]

Hi all.

I've been playing with connecting our stand alone repeater up to one of 
the AllStar hubs in the afternoons when the repeater is usually very 
quiet on local RF. I've got all of the cron entries sorted and 
everything works well. Before I make it all live, is there any way I can 
only get the script to run if there are no RF users on the repeater so 
it does not connect them up half way through a QSO? I already have voice 
announcements for 10 minutes, 5 minutes and 1 minute before the 
connection runs but it would be great to only allow the connection once 
the repeater has not been in use for x minutes.

Failing that, is there a way to set up a short code that an RF user can 
dial to abort the auto connect before it runs? I could create a voice 
file that outputs something like 'dial *73 on your DTMF keypad to abort 
the connection'. I know I can do this once the repeater has connected 
but it would be a nice feature to be able to stop the connection.

Is any of that possible?

Thanks,

Matt
