Sender: hackers-owner@freebsd.org Precedence: bulk I have asked this before on c.o.3.q, but I got no answers. I would like to set up my system such that I can call in when the one modem is not in use for calling out. My understanding from the sio man page is that it should be possible. However, whe I start a getty on ttyd0, cu will give 'Line in use': /usr/u/burg# uname -v FreeBSD 2.0-RELEASE #5: Fri Dec 9 15:47:05 MET 1994 burg@burgpc.is.ge.com:/mnt/src/sys/compile/VDB /usr/u/burg# ps ax | grep getty 112 v1 Is+ 0:00.09 /usr/libexec/getty Pc ttyv1 113 v2 Is+ 0:00.10 /usr/libexec/getty Pc ttyv2 162 00 Is+ 0:00.07 /usr/libexec/getty std.38400 ttyd0 /usr/u/burg# ls -l /dev/ttyd0 /dev/cua00 crw-rw-rw- 1 uucp dialer 28, 128 Dec 20 16:35 /dev/cua00 crw-rw-rw- 1 root wheel 28, 0 Dec 21 09:18 /dev/ttyd0 /usr/u/burg# /usr/u/burg# cu -s38400 -l/dev/cua00 dir cu: /dev/cua00: Line in use /usr/u/burg# Am I doing something wrong, or is what I want simply not possible?
