2. Once the connection is established, the line remains active until you tell the
software to hang up the line. This avoids the lengthy initialization process every
time you access an online feature.

modem; press [F5] No (or [Esc] ) to leave the connection active for future
communications.
§ Access the Terminal Utility Program and press [Alt-H] to hang up the
modem. (For more information, see the Terminal Utility Program section on
page 15-39 .)

Common Problems
The following is a list of common problems encountered when using modems for
communication.
•
The modem dials, but the connection with the other modem is not made. Make
sure the other modem is set to auto answer.
•
Settings are not consistent throughout the communications line. Remember
that all communications settings (e.g., duplex, error checking, baud rate, parity,
etc.) must be identical for both modems, your destination device (e.g., KF3, KE,
Channel Zero), and the Configure Online Communications Hardware
configuration screen. If any of these settings is inconsistent, communications will
not be possible.
