Description Craig Leres freebsd_committer 1997-07-18 04:20:02 UTC 
	When running the current release of xntp (3-5.90), xntpd syslogs
	repeated errors:

	    Jul 17 12:29:24 meg xntpd[1714]: synchronized to GPS_JUPITER(0), stratum=0
	    Jul 17 12:29:25 meg xntpd[1714]: input_handler: select() returned 0
	    Jul 17 12:29:56 meg last message repeated 31 times
	    Jul 17 12:31:57 meg last message repeated 121 times
	    Jul 17 12:41:58 meg last message repeated 601 times
	    Jul 17 12:51:59 meg last message repeated 601 times
	    Jul 17 13:02:00 meg last message repeated 601 times
	    Jul 17 13:12:01 meg last message repeated 601 times
	    Jul 17 13:22:02 meg last message repeated 601 times
	    Jul 17 13:32:03 meg last message repeated 601 times
	    Jul 17 13:42:04 meg last message repeated 601 times

	These are due to the DCD line being toggled once per second.

Fix: The appended patch to kern/tty.c cures the problem.

RCS file: RCS/tty.c,v
retrieving revision 1.1
How-To-Repeat: 
	Run the lastest xntpd with a refernece clock that uses
	the DCD line to import the PPS signal; watch the syslog.
