[arm-allstar] half duplex node linking to a repeater

[Sione Ragle]

Hi I have a node that is used for linking my local repeater to another 
repeater using a half duplex node.

Some repeaters I link do have a long hang time and I find that I can't 
keyup the link until the remote repeater is unkey. Is there a way to 
make it so I can key up the half duplex node at any time I want and not 
wait for the carrier to drop from the remote end?

Thanks,
