- This can sometimes be one of the following:
-
- The modem is timing out waiting for the carrier. This is evidenced by
- seeing "NO CARRIER" from the modem while uucico is waiting for
- "CONNECT". You can fix this by extending the timeout on the modem with
- an ATS7=60 or ATS7=90 in the dialer script.
-
- uucico times out waiting for "CONNECT". uucico built-in timeouts are
- often not enough with multiple modem speeds, long distance companies,
- MNP protocol negotiations. The time uucicio will wait can be artifically
- extended by adding delays to the dial script so it looks like it
- took longer to dial than it actually did.
-
- ... ATDT\D\r\d\d\d\d\d\d\d\c CONNECT
-
- The imbedded <return> gets the modem dialing right away but uucico doesn't
- start waiting for "CONNECT" until all the delays (\d) have finished.
