System: NetBSD cougar 1.0A NetBSD 1.0A (COUGAR) #5: Fri Aug 11 22:14:30 MET DST 1995 matthieu@cougar:/usr/src/sys/arch/i386/compile/COUGAR i386


>Description:
	1. If 'eofwrite' is undefined, tip dumps core when using the ~> 
           file transfer command
	2. If a stale lock exists tip cannot override it, emitting the 
           following message:

		Stale lock on tty01 PID=18111... overriding.
		/var/spool/lock/LCK..tty01: Invalid argument
		Can't seek lock file.

>How-To-Repeat:

	start tip with a remote entry that does not define the 'oe'
	capacity, for instance:

		tty01:dv=/dev/tty01:br#9600:pa=none:
	
	then send a file using ~>

	after the tip crash, try to restart it to observ the 2nd
	problem.

>Fix:
	Apply this patch:
