[nos-bbs] slattach /dev/ptypatach, pseudo ttys and *BSD

[Torsten Harenberg]

Dear all,

happy new year to all of you!

I know that this is a bit off topic, but is there anybody out there with 
experience running slattach on a pseudo tty on *BSD? While this seems to 
be no problem on Linux, it seems that all BSDs lack functionality:

on Linux:

up:/common/home/harenber # /sbin/slattach /dev/ptypa &
up:/common/home/harenber #

/var/log/messages:

Jan  8 00:06:27 up kernel: SLIP: version 0.8.4-NET3.019-NEWTTY (dynamic 
channels, max=256) (6 bit encapsulation enabled).
Jan  8 00:06:27 up kernel: CSLIP: code copyright 1989 Regents of the 
University of California.
Jan  8 00:06:27 up kernel: SLIP linefill/keepalive option.        Jan  8 
00:06:27 up kernel: SLIP: version 0.8.4-NET3.019-NEWTTY (dynamic 
channels, max=256) (6 bit encapsulation enabled).
Jan  8 00:06:27 up kernel: CSLIP: code copyright 1989 Regents of the 
University of California.
Jan  8 00:06:27 up kernel: SLIP linefill/keepalive option.

...


But on *BSD (tried NetBSD and Mac OS X, the latter one is my primary 
target and as there is no JNOS tun support on this port, I wanted to use 
a SLIP line over a pseudo tty):

[23:20] root at Torsten-Harenbergs-PowerBook:~ $ slattach ptypa
ioctl(TIOCSETD): Operation not supported by device


I googled quite a bit and found old threads explaining that *BSD doesn't 
support all ioctl's:

http://groups.google.com/group/mpc.lists.freebsd.questions/msg/419947e9e5f589ee?dmode=source&hl=de

But this posting is allready ~8years old, so I hope there is somebody 
out there who found a way. As this is a very rare use case, I hope to 
find somebody here instead of asking on some Mac mailing lists/usenet 
groups.

Any hint (maybe there is another way to attach JNOS to the net?) very 
much appreciated...

Best regards,

   Torsten DL1THM
