Output Selected File; Output All Files; Output File With Acknowledgement; Read-In Selected File - HEIDENHAIN TNC 415 Technical Manual

Output selected file

The TNC outputs all of the program lines in order. The peripheral unit can stop transmission with
character <DC3> and start it again with character <DC1>.

Output all files

The procedure is similar to the protocol described in paragraph 3.1.2 "Outputting a selected file". The
TNC arranges all the programs in order and transmits them. No control character is sent between
the individual files.

Output file with acknowledgement

The programs are transmitted in the same way as described in section 3.1.3 "Outputting all files".
However, an acknowledgement is expected from the user between the transmission of individual
programs.

Read-in selected file

If a file is read in from a peripheral unit (e.g. a PC), the corresponding name must be indicated in the
TNC and the TNC be started first, i.e. the TNC outputs the character <DC1>. Transmission of the file
concerned is then initiated at the peripheral unit.
When the entire file has been transferred, the TNC sends character <EOT>.
