Configuring Lines
56 IOLAN Device Server User’s Guide, Version 1.0
Break
Specifies how a break is interpreted:
z None—The Device Server ignores the break key completely and it is not
passed through to the host. This is the default setting.
z Local—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.
z Remote—When the break key is pressed, the Device Server translates this
into a telnet break signal which it sends to the host machine.
z Brkintr—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
-ignbrk and brkintr are set).
Hotkey Prefix
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 .
Flowin
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 .
Flowout
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 .
Reset
Resets the terminal type connected to the line when a user logs out.
Keep Alive
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.
MOTD
Enables/disables the message of the day on the line.
Lock
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.
