The original poster, I believe was having problems with lock files. Diald
daemon trying to lock the device and finding /var/lock/LCK..cua3 owned by
another PID. From the device name, it appears the OS is Linux (FreeBSD
serial device names are /dev/cuaa[0-3], cuaia[0-3], cuala[0-3]).
Until now, I was under the impression, that once a specific device is
locked it cannot be used by another process (to ensure availablity of
service by the locking process). If the **same** device can be used by
(each using it's locking mechanism) mgetty/diald/minicom respectively then
I am interested in finding out how it can be done. I would appreciate if
you could share your configuration info for the above applications. It
would be another selling point for Linux.

I have not seen any clear views on this. Some say /dev/cua* are the old
serial devices provided for backward compatibility and that only /dev/ttyS*
should be used to call out/in. Some say, use ttyS* to call in and cua* to
call out. Fr FreeBSD serial devices see above.
