When TERM for UNIX returns a “device busy” error, but there are no lockfiles, there is a permission problem.  Verify the following:

• Permissions on /usr/bin/callin and /usr/bin/callout must be 4755 (-rwsr-xr-x).
• Permissions on the full structure of /usr/spool/uucp or /var/spool/uucp (Linux) must be at least 666 (-rw-rw-rw-). The directory itself, plus every directory and file within it, must have those permissions or higher. Lockfiles are placed in this directory.
• Permissions on the tty port itself must be at least 666 (-rw-rw-rw-).
