# This script is run from cron, and will check for previous auto connection
# by looking for the 'flag' file $LOCAL/ra_connect_id which is created by the
# reflect_auto_connect script.  It is a copy of the 'active' flag set at the
# time of connection. If the flag matches the current active flag the connection
# is cleared down.  This script will clear the ra_connect_id flag if it exists
# and clear the CWID block if it exists.
#
# V1.0 02/02/2009 - VK8SJ - Original version
# V1.1 09/02/2009 - VK8SJ - Add CWID check & restore
# V1.2 12/04/2010 - VK8SJ - Add check for auto-reconnect
# V2.0 25/04/2010 - VK8SJ - Add restore timeout value
# V2.1 24/03/2019 - VK2YLD - Add check to re-enable DTMF controls
