- I'm having a little trouble with uucp. My company runs a small
- network (not connected to the Internet) using SCO Xenix 386GT R
- 2.3.4h under a vertical POS application. Daily fiscal information
- is sent to the central office utilizing uucp via a dialer script
- written by the POS vendor. Telebit T1000 modems are at all sites.
- Data entry commenced, the pigs danced, and communications were fine
- for about 3 months...then the gremlins appeared. The daily
- transfer option in the POS menu started reporting failures to
- communicate with one site.
-
- I can manually login to the uncooperative site, but uucp stands
- firm in its defiance. The Systems, Permissions, and Devices files
- all check out. Poking around, I notice the LCK file hasn't been
- deleted by uucico, so I do it. As I watch, a new process invoking
- the dialer script is initiated, with a PPID of the "- tty1A m"
- process created by init. As root at the remote site, I can delete
- the LCK..tty1a file in /usr/spool/uucp, and within a few ticks the
- system generates it again. Incidentally, this has been the case
- with every combination of powering up the Telebit T1000 modem in
- conventional/enhanced mode - tty1a/tty1A. Shutdown and reboot
- doesn't change anything.

- The following is the log file generated by uutry on the remote
- site:
