Socat server and client for use with NTP's type 18 ACTS driver.

	#This is currently used by an NTP server to access a V.92 modem over the LAN to dial the NIST ACTS.
	#The options here work using a USR5686G modem over a PL2303 USB to RS232 adapter with NTP 4.2.8p8.
	#NTP expects a device called "acts1" at 19200 baud. You should adjust the port number, character device file, baudrate, and lockfile to suit your environment.
	#NTP will not autobaud after a successful connection using this method. The modem init string in ntpd/refclock_acts.c must be edited to lock the modem to 19200 baud.
	#A ping test was added to the client to limit the number of retries it makes during a network outage.
	#These are placed in startup scripts run by a cronjob.
