Specifications
If a command is unknown or a parameter is incorrect, the output "ERR." is given at the
beginning of the line, followed by a description of the fault. Successful instructions
without special return value will be acknowledged by "OK.". All other return values are
output within a single line. There are of two exceptions:
1. Some configuration changes, that affect TCP / IP and UDP, need a restart to be ap-
plied. These parameters are output on two lines. In the first line the current value is
shown, on the second row the value after a restart. In the "Cmd Overview" table this
is marked with "Note 2".
2. Other configurations (such as the assigned IPv6 addresses) have several values that
can change dynamically. This is marked with "Note 3" in the "Cmd Overview" table.
Numerical Returns
For parameters that support constants, these constants are output as return values. To
better deal with scripting languages, it may be easier to work only with numerical re-
turns. The command "
vt100 numeric set ON
" enables that only numerical values
appear.
Comments
If you use a tool to send an entire file of commands via Telnet, it is helpful, if you can
place comments in there. Beginning with the comment character "#", the remaining con-
tents of a line is ignored.
Telnet
If the configuration "Raw Mode" is turned off, it is tried to negotiate the Telnet configura-
tion between client and server using IAC commands. If this fails, the editing functions are
not active, and the "Activate echo" option determines whether the characters sent to the
Telnet server will be returned. Normally the client begins with the IAC negotiation. If this
is not the case with the client, the device configuration "Active negotiation" should be
turned on.
Raw Mode
If you want to use the console only automated, it may be advantageous to set the con-
figuration "Raw mode" to "yes" and "Activate echo" to "no" to. Then there is no interfer-
ing interaction with the editor functions and the is no need to filter the sent characters to
process the return values.
If in the console "Raw mode" is activated but not in the used Telnet client, the IAC
commands sent at the beginning can appear as interfering characters in the command
line (partially invisible).
Editing
The following edit functions are available when the terminal supports VT100, and Raw
Mode is deactivated. Entered characters are inserted at the cursor position.
