Lisa Compact 53
To program settings and control the operation of the Lisa, the Lisa Configuration Tool sends textual
commands to the Lisa. In return the Lisa will send back a textual message to indicate whether the setting
was applied.
For most settings, the current setting can be read by issuing the command without the parameters. For
example, to see which Telnet settings are used, the command '
telnet
' (without the quotes) can be used.
When the Lisa receives the command, it returns the current value of the setting.
In Command overview list the complete list of commands is documented, including examples. A device
reset may be required to apply changes in settings. The “reset” will power the Lisa Compact device
back on. The Lisa needs to be powered on after a "reset", using the “pw 1” command .
See Lisa Configuration Tool for more information.
13.4 Telnet
A Telnet client is available on all (TCP/IP-enabled) computer platforms. Therefore, it makes sense to
support this protocol on the Lisa as well. Because a limited set of Telnet features are supported by the
Lisa, Telnet should be regarded as a command interface over port 23 for the Lisa.
When Telnet is enabled, the Lisa is constantly waits for an incoming Telnet connection. If the
connection is made, the Lisa can be controlled by sending commands. The list of available commands is
listed in the
Command overview list .
To disconnect from the Lisa, type 'quit' (without the quotes).
Port use
Telnet on the Lisa uses port 23 (the standard port for Telnet). Since the Lisa acts as a server in this
case, inbound TCP network connections on port 23 to the Lisa are required for Telnet to work. Port-
forwarding is required when the Lisa must be reachable from outside the local area network.
The Telnet feature on the Lisa is not protected by a username and/or password. Be careful when
making the Lisa accessible from outside the local area network.
13.5 Command overview list
The list below presents all available commands for the Lisa. Examples of using these commands are
given in
Examples of sending commands , links to these examples are offered in the overview below as
well.
By default the Lisa sends a response when it receives a command. In case the Lisa is required to report
a setting, it will send these settings back. In case the Lisa is required to change a setting, it will respond
with an “OK” when successful. When the Lisa fails to execute the command, it will send “ERROR” back.
For most settings it is required that the device is reset to apply changes to settings. The Lisa
Configuration Tool always will send the <reset> command after it has program settings to the device.
