Output all files
The files are output in order, as in section 4.1.2 "Outputting a selected file". Control characters
<ETX><EOT> are sent to the peripheral device between files.
Output file with confirmation
In this mode, a question is asked before each file output in order to determine whether or not the
file is to be output. After each file, control characters <ETX> and <EOT> are sent, as in section 4.1.3
"Outputting all files". If output of a file is not desired, the TNC immediately offers the next file in the
directory for output.
