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 SP to the operating system that agreeing terminal emulators becomes important.
The server’s operating system has some built-in terminal emulators. Your server 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 that the key
assignments and responses match. This ensures successful communications and
control.
For optimum formatting, choose line wrap in your terminal emulator setup.
Recovery Procedures
Line noises, power surges, and so on, 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.
