60 CHAPTER 4: TERMINAL SERVICE
Typical Example of
Terminal Message
Service Configuration
# Input the send command in system view.
[Router] send
Enter message, end with CTRL/Z; abort with CTRL/C:
# Input the contents of the message that the terminal will send.
hello world # (Enter <Ctrl+W> to terminate the message input )
end message? [confirm]
Press Enter, Ctrl+W, y, or Y to confirm the sending. Press Ctrl+C or other characters
to give up the sending.
Dumb Terminal
Service
When the asynchronous serial port (such as synchronous/synchronous serial port,
AUX port) of the router operates in flow mode, the command line interface (CLI)
of the router can be used to carry out configuration of the router. This is achieved
by directly connecting the RS-232 serial port with the asynchronous serial port of
the router. This is called the dumb terminal operation mode.
As shown in the diagram below, the user can connect with any asynchronous
serial port and log in to the router by running the hyper terminal on PC to carry
out the configuration management of the router.
Figure 26 Configuration management through dumb terminal
The typical method of terminal access is:
■ The asynchronous port working under the flow mode is connected to the
RS-232 serial port via dedicated line to enter the router command line interface
thereby providing another mode of configuring routers besides the mode of
console port and Telnet mode.
■ Based on the dumb terminal, other applications can be built, for instance,
logging on to other equipment by executing the Telnet command.
Configure Dumb
Terminal Service
Follow these steps to configure a dumb terminal service.
1 Configure dumb terminal service
For the synchronous/asynchronous serial port, physical-mode async, async mode
flow
, and undo modem should be set first.
Perform the following configuration in the interface view.
