interrupt on only the first ring, set Ring Indicate Power-On to start on the first ring.
Otherwise, you may choose to start Ring Indicate Power-On on any ring count that
makes your operation convenient.
Terminal Emulators:
The Service Processor is compatible with simple ASCII
terminals, and therefore compatible with most emulators. It is for the cases when a
remote session is handed off from the Service Processor to the operating system
that agreeing terminal emulators becomes important.
The server's operating system has some built-in terminal emulators. You may also
have a commercially available terminal emulation. It is important that the local and
host computers select the same or compatible terminal emulators so the key
assignments and responses match. This assures successful communications and
control.
For best formatting, choose line wrap in your terminal emulator setup.
Recovery Procedures:
Line noises, power surges, etc., can sometimes cause
your modem to enter an undefined state. When it is being used for dial in, dial out
or Ring Indicate Power-On, your modem is initialized each time one of these actions
is expected. If one of these environmental conditions occur after your modem has
been initialized, it may be necessary to recover your modem to a known state.
