HAPTER ERMINAL CCESS ONFIGURATION
Terminal display language configuration
The initiator generally sends some unsolicited information, such as menus and link
establishment information, to the terminal. To meet different language needs, the
prompt information can be displayed in either English or Chinese (the default).
Screen saving
Some types of terminals provide the screen saving function, enabling the terminals
to switch to the corresponding screen upon receiving the specified screen code,
such as E!10Q. When you perform VTY service fast switching, the router sends a
screen code to the terminal, which switches to the corresponding operation
interface after saving the current operation interface.
To save the screens of multiple VTYs, you need to set different screen codes for
these VTYs and make sure the number of screen codes supported by the terminal
is greater than the number of configured VTYs. Note that this function needs
terminal support. In addition, the screen codes that can be identified vary with
terminal types and the number of supported screen codes may also be different.
For details, refer to the corresponding terminal manuals.
Read blocking
Terminal data read blocking means that, if the router has not sent data received
from the terminal successfully, the router stops receiving data from the terminal
until all the data is sent successfully. Generally, you need to enable this function
only when the transmission rate between the router and the FEP is less than that
between the router and the terminal.
Terminal reset
In case the terminal fails to communicate with the receiver, you can press the
terminal reset hotkey on the terminal so that the initiating router will first
disconnect and then reestablish the TCP connection with the receiver.
Connectivity test
You can set the terminal test hotkey on the router. By pressing the test hotkey on
the terminal, you can test the connectivity between the terminal and the router
and the TCP connectivity between the terminal and the FEP.
Data send delay
After data send delay is configured on the router, upon receiving data from the
terminal, the router will not send the data to the FEP until the specified period
elapses. This allows the information collected within the specified period to be
sent together, thus increasing bandwidth utilization.
TCP buffer parameter configuration
Terminal access allows you to perform two types of buffer parameter
configuration operations: TCP buffer and terminal buffer. TCP buffer is used to
store the data exchanged between the sender and receiver. Terminal buffer is used
to store the data exchanged between the sender and the terminal.
You can set some parameters of TCP connection, including receive buffer size,
transmit buffer size, non-delay attribute, keepalive interval and transmission times.
