Protecting and erasing programs in $MDI
The $MDI file is generally intended for short programs that are only
needed temporarily. Nevertheless, you can store a program, if
necessary, by proceeding as described below:
Select the Programming and Editing mode of
operation.
To call the file manager, press the PGM MGT key
(program management).
Move the highlight to the $MDI file.
To select the file copying function, press the COPY
soft key.
Enter the name under which you want to save the
current contents of the $MDI file.
TNC 410: Start copying by pressing the ENT key
TNC 426 B, TNC430: Press the EXECUTE soft key to
start copying
To close the file manager, press the END soft key.
Erasing the contents of the $MDI file is done in a similar way: Instead
of copying the contents, however, you erase them with the DELETE
soft key. The next time you select the operating mode Positioning with
MDI, the TNC will display an empty $MDI file.
For further information, see “Copying a single file,” page 58.
