Line Commands
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.
data-loggin
When enabled, serial data will be buffered if the TCP connection is lost. When the TCP
connection is re-established, the buffered serial data will be sent to its destination (this
option is not available when
Monitor DSR, Monitor DCD, or Multihost is enabled).
The data buffer is 4K for desktop models and 32K for rack mount models. If the data
buffer is filled, incoming serial data will overwrite the oldest data.
The default is
off.
idle-timer
Enter a time period, in seconds, for which the Idle Timer will run. Use this timer to
close a connection because of inactivity. When the
Idle Timer expires, the IOLAN will
end the connection. The maximum value is 4294967 seconds (about 49 days). The
default value of
0 (zero) means the Idle Timer will not expire, so the connection is
permanently open.
initial
Specifies the initial interface a user navigates when logging into the line; either the
Menu or a prompt for the CLI. The default is CLI.
initiate-connection
Initiates a Telnet connection to the specified host when any data is received by the serial
port or when the specified character is received by the serial port (direct Telnet only).
internet-address
Used with reverse sessions, users can access serial devices connected to the IOLAN by
the specified Internet Address (or host name that can be resolved by a DNS). You must
reboot the IOLAN for the
Internet Address to take affect (the kill line option does not
apply to this parameter).
keepalive
Enables a per-connection TCP keepalive feature. After the configured number of
seconds, the connection will send a gratuitous ACK to the network peer, thus either
ensuring the connection stays active OR causing a dropped connection condition to be
recognized.
This parameter needs to be used in conjunction with server parameter,
monitor-connection-every. The interval determines how long the IOLAN will wait
during inactivity before "testing" the connection. It should be noted that if a network
connection is accidentally dropped, it can take as long as the specified interval before
anyone can reconnect to the serial port.
line-name
Provide a name for the line so it can be easily identified.
