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
contents of a line is ignored.
Telnet
If the configuration "Raw Mode" is turned off, it is tried to negotiate the Telnet configur-
ation 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 negoti-
ation. 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.
Keys Function
Left, Right moves cursor left or right
Pos1, End moves cursor to the beginning or end of line
Del deletes character under the cursor
Backspace deletes character left of cursor
Up, Down shows input lines history
Tab, Ctrl-Tab completes the word at cursor
Ctrl-C clears the line
When a shrink of the terminal window leads to the result, that the input line ex-
tends over multiple lines on the terminal, the editing does not work reliably.
