>/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? Perhaps getty has opened /dev/ttyd0. Use "fstat | grep ttyd0" and/or "ps -laxt d0" to see if /dev/ttyd0 is open. Carrier must be configured correctly for previous gettys to be killed. Check for junk in /var/spool/lock. getty doesn't use lock files so there should be no locking conflicts between in and cu. Another bug: if I run cu while rlogin'ed, it connects correctly, but when I type "~.", both cu and rlogin exit. Bruce
