3Com 10014299 Terminal Message, Service, On one router, Set the attributes of terminal service

58CHAPTER 4: TERMINAL SERVICE

Features of Terminal The 3Com Router supports remote configuration on the router via asynchronous Service at Async Serial serial port (including synchronous/asynchronous serial port, 8/16 asynchronous

Port serial port, and AUX port). Please refer to Chapter 2 “3Com Router User Interface”of this manual for the specific method to establish the configuration environment.

The remote terminal service features of the asynchronous serial port are shown in the following table. Parameters of the terminal program running on the computer should be set according to this table, and parameters such as baud rate, data bit, parity check and flow control should be consistent with those of corresponding router interfaces.

Table 38 Remote terminal service features of the asynchronous serial port

Service	Features
Echo mode	No local echo
Terminal emulation type	VT100
Baud rate	Consistent with interface configuration, 9600 bps by default
Data bit	Consistent with interface configuration, 8 bits by default
Parity check	Consistent with interface configuration, no parity by default
Stop bit	Consistent with interface configuration, 1 bit by default
Flow control	Consistent with interface configuration, no flow control by
	default

Set the Attributes of Usually, the terminal user connected via the console port can last for 3 minutes. Terminal Service The time for the dumb terminal user can last for 10 minutes. For the user who

uses the dummy terminal in dial-up mode, the disconnection timeout is 6 minutes but the user can disable this function by using the undo idle-timeoutcommand so that all the terminal users will never be disconnected.

Perform the following configuration in system view.

Table 39 Set the attributes of terminal service

Service	Attribute
Enable the function of timeout disconnection from the	idle-timeout
terminal user
Disable the function of timeout disconnection from the	undo idle-timeout
terminal user

By default, the system will enable the timeout disconnection of the terminal user.

Terminal Message	Whenever the terminal users that log into the same router want to communicate
Service	with each other, they can use the terminal message service to send messages. The
	remote users can telnet onto the local router to transmit information such as
	simple configuration files and description characters that are not easily expressed
	through telephones among terminal users, using the send command. It is much
	more convenient than email. Ensuring information security and reliability, the
	terminal message service fulfills information interaction among multiple terminals
	on one router.
	For example, user A and user B respectively log into Router A and Router B. If user
	A wants to communicate some information (such as configuration information)
