>Release:        FreeBSD 3.0-971208-SNAP i386
>Environment:

	Straight 3.0-971208 installation with stock slattach.

>Description:

	If I run my SLIP script (which invokes slattach) from inside an
	xterm, it works fine (doesn't log errors in /var/log/messages, 
	and does correctly create the var/run/slattach.cuaa1.pid pidfile.

	However, if I run my SLIP script from my window manager menus
	(i.e. not inside a vtty), then slattach logs the following error
        in /var/log/messages:

             slattach[15882]: ioctl(TIOCSCTTY): Operation not permitted

        and does not create a /var/run pidfile.

	3.0-current slattach otherwise appears to work; it just doesn't 
	create the pidfile that I use in other scripts & cron jobs.
 
>How-To-Repeat:

	Here is a clip from my "slip-on" script that shows how I invoke
        slattach (error checking removed for simplicity):

             #!/bin/sh
	     ...
	     exec 0< /dev/cuaa1
	     exec 1> /dev/cuaa1
	     chat TIMEOUT 2 "" AT OK AT OK
             chat "" "$INITSTRING" "OK" "AT$DIALSTRING" ...<request slip cmds>
             slattach -h -c -s 57600 /dev/cuaa1 > /dev/null 2>&1 &


>Fix:
	
	Not known.
