Keystroke log
The TNC stores keystrokes and important events (e.g. system
startup) in a keystroke log. The capacity of the keystroke log is
limited. If the keystroke log is full, the control switches to a second
keystroke log. If this second file becomes full, the first keystroke
log is cleared and written to again, and so on. To view the keystroke
history, switch between CURRENT FILE and PREVIOUS FILE.
Press the LOG FILES soft key
Open the keystroke log file: Press the KEYSTROKE
LOG FILE soft key
If you need the previous log file: Press the
PREVIOUS FILE soft key
If you need the current log file: Press the
CURRENT FILE soft key
The TNC saves each key pressed during operation in a keystroke
log. The oldest entry is at the beginning, and the most recent entry
is at the end of the file.
