System: NetBSD rainier.reedmedia.net 1.6 NetBSD 1.6 (JCR-20020927) #3: Sat Sep 28 13:40:20 PDT 2002 reed@rainier.reedmedia.net:/usr/src/sys/arch/i386/compile/JCR-20020927 i386
Architecture: i386
Machine: i386
>Description:
I frequently used slattach under 1.4.x and 1.5.x, but now doesn't
work under 1.6. (I have systems that slip is the only network connection.)

I tested on two different systems with 1.6 (to 1.5.3) and they don't work.
No errors, just no traffic. netstat tells me that it is receiving traffic
when I ping it, but nothing returns:

sl0*  296   <Link>                               57722          0

slip works fine for 1.5.3 to 1.5.3 (on same hardware same day).
>How-To-Repeat:
On one i386 system (1.5.3):
 slattach -l -h -s 115200 /dev/tty00
 ifconfig sl0 192.168.0.111 192.168.0.110
 route add default 192.168.0.110

And then on the other i386 system (1.6):
  slattach -l -h -s 115200 /dev/tty00
  ifconfig sl0 192.168.0.110 192.168.0.111

>Fix:
I don't know.
I don't see any change in slattach(8) that matters.
I am not sure of any ifconfig(8) changes that affect it.
I do see a lot of changes in if_sl.c.
