Terminating a

68K Monitor

TELNET Session

While any application running in the system can activate the 68K Monitor, only one instance of the monitor can be active at any one time.

If a second application attempts to start the 68K Monitor, it will refuse the second application’s request.

The prompt produced by the 68K Monitor depends on the hardware platform and the mode the device is in.

As examples:

The table below shows examples of the prompts that you may see on various devices in different modes of operation.

	When this	is operating out of…	you will see this
	device…		prompt…

	D25	BootROM (this is known as the System	D25S>
		Monitor)

		FLASH (this is known as the Application	D25A>
		Monitor)

	D20 ME	Service Mode	D20MES>
	(CCU Base)
	(CCU Base)	Active Mode	D20MEA>
		Active Mode	D20MEA>

	CPM or	Any Mode	D20M>
	D20M(++)

The 68K Monitor will detect a loss of connection in a TELNET session and will end the monitor session, allowing a new connection to be established.

The 68K Monitor itself never terminates or initiates a TELNET session. Whatever process starts the 68K Monitor handles this functionality.

Auto-Logout Timer

Since only one 68K Monitor session is allowed at a time, it automatically terminates a session if no input is received for 5 minutes (default) or after a user-programmed interval.

Refer to: Page 3-4,AL - Change Auto-logout Timer for details about how this timer can be changed.
