# description:	Reads the Linux system clock (localtime) then generates
#		the DTMF sequences to set the RLC-3 repeater controller
#		clock's Date and Time.
# notes:	Uses the fastdtmfdial script if available; otherwise,
#		the dtmfdial script is used. fastdtmfdial has settable
#		speed parameters and can send the DTMF tone very quickly.
#		See the node owner's list for messages on how to create
#		the fastdtmfdial script on your system.

# history:
# 20020628	kc6hur	Original release
# 20020903	kc6hur	Modified to automatically use fastdtmfdial if
#			available.
