terminal-number: Terminal number, ranging 1 to 255.

Use the rta terminal command to apply a template on the interface.

Use the undo rta terminal command to cancel the template application.

By default, no template is applied on the interface.

A terminal can be created only after the configured template is applied on the 
corresponding interface, so as to implement terminal access. Use the 
terminal-number argument to specify the terminal number. An interface can be 
connected to only one physical terminal. The router identifies physical terminals by 
terminal number.

Note that at least one VTY should be configured in the terminal template for the 
template to be applied on the interface. This command supports asynchronous 
serial interfaces, synchronous/asynchronous serial interfaces, and AUX interfaces. 
This command can be configured on a synchronous/asynchronous serial interface 
only when the interface operates in the asynchronous mode.

# Apply the terminal template abc with the terminal number of 1 on the interface.

<Sysname> system-view

[Sysname] interface async 1/1

[Sysname-rta-async1/1] rta terminal abc 1 

sendbuf bufsize size

Terminal template view

size: Maximum size of data sent to the terminal at one time, in bytes, ranging 2 to 
500.

Use the sendbuf bufsize command to configure the maximum size of data to be 
sent to the terminal.

Use the undo sendbuf bufsize command to restore the default.

By default, the maximum size of data to be sent to the terminal at one time is 500 
byes.

The router sends data in packets to the terminal. The sizes of the sent packets are 
different. Use the size argument to specify the maximum data packet size.

# Configure the maximum size of data to be sent at one time as 200 bytes.
