Example:
CB9000> set terminal timeout system 10
After you set the timeout, the terminal automatically logs you out of the
system if there is no terminal (keyboard) activity for the period of time
that you have specified. In this example, logout occurs after 10 minutes
of keyboard inactivity.
Setting Terminal Type
Use the
set terminal console terminal_type
command to define a
terminal type for use with outbound Telnet sessions. The system sends
the terminal type to the device that is connected to the EME when
initiating the Telnet session. The terminal type setting enables the device
to send the proper control sequences to the EME, which appear on the
EME terminal.
The following command defines the terminal type as a VT100 terminal on
the console port:
CB9000> set terminal console terminal_type vt100
Terminal type changed.
Troubleshooting the
Terminal Interface
Table 22 lists some common problems that can occur as you configure
the EME to communicate with a terminal.
Table 22 EME Terminal Interface Problems
Symptom Corrective Action
Nothing appears on the screen
(screen is blank).
■
Make sure that the RS-232 cable meets the
specifications in Chapter 2.
■
Make sure that the RS-232 cable is securely
connected to both devices.
■
Verify that the baud rates match for the
terminal and the EME. (See Chapter 4)
Garbled characters appear on
the screen. Verify that the EME and the terminal settings
match for baud, data bits, stop bits, and parity. The
default baud rate is 9600, 8 data bits, no parity, 2
stop bits.
The

command does not
work.
Make sure that you are logged in as
admin
and
that you are connected to the primary EME (display
shows
Rdy
).
You use abbreviated input, but
pressing the spacebar does not
complete the command. Enter enough characters for the EME to distinguish
between different commands and options. Enter
?
for a list of available options.
