- About the only thing I've ever found that makes the OS keep

- thinks a modem has connected and someone wants to log in. This
- CD (on pin 8) could be either the modem is set to force CD on, or
- the cable pinning is wrong.

- If the site used to work fine, and the cable has not been
- changed, I would suspect the modem is setting CD high.
