Request External Directory - HEIDENHAIN TNC 415 Technical Manual

Request external directory

Using the soft key "Show ext. directory", the list of file names can be requested from an external
memory and displayed in the TNC.
If the external directory is requested, the TNC sends control character <DC1>.
If the request is immediately interrupted with the END key, the TNC sends characters <ETX><EOT>
and no directory is read in.
If the request is not interrupted, the peripheral unit sends all of the external programs in order. Their
names are then shown in the TNC.
