Specifies how a break is interpreted:

zNone—The Device Server ignores the break key completely and it is not passed through to the host. This is the default setting.

zLocal—The Device Server deals with the break locally. If the user is in a session, the break key has the same effect as a hot key.

zRemote—When the break key is pressed, the Device Server translates this into a telnet break signal which it sends to the host machine.

zBrkintr—On some systems such as SunOS, XENIX, and AIX, a break received from the peripheral is not passed to the client properly. If the client wishes to make the break act like an interrupt key (for example, when the stty options -ignbrkand brkintr are set).

The prefix that a user types to lock a line or redraw the Menu. The default value is hex 01, which corresponds to Ctrl-a(^a) (hex value 02 would be Ctrl-b (^b), etc.):

z^a l—(Lowercase L) Locks the line until the user unlocks it. The user is prompted for a password (any password, excluding spaces) and locks the line. Next, the user must retype the password to unlock the line.

z^r—When you switch from a session back to the Menu, the screen may not be redrawn correctly. If this happens, use this command to redraw it properly.

You can use the Hotkey Prefix key to lock a line only when the Line Lock parameter is On.

Determines if input flow control is to be used. Default is On. This is active only when Line Flow Control is set to Soft, Hard, or Both.

Determines if output flow control is to be used. Default is On. This is active only when Line Flow Control is set to Soft, Hard, or Both.

Resets the terminal type connected to the line when a user logs out.

Enables a per-connection TCP keepalive feature; after approximately 3 minutes of network connection idle time, the connection will send a gratuitous ACK to the network peer, either ensuring the connection stays active OR causing a dropped connection condition to be recognised by the reverse raw service.

Applications using this feature need to be aware that there might be some considerable delay between a network disconnection and the port being available for the next connection attempt; this is to allow any data sent on prior connections to be transmitted out of the serial port buffer. Application network retry logic needs to accommodate this feature.

Enables/disables the message of the day on the line.

When enabled, the user can lock his terminal with a password using the Hotkey Prefix (default Ctrl-a) ^a l (lowercase L). The Device Server prompts the user for a password and a confirmation.
