Here's a hint if you use CodeConsole:

[gtj0]

# apt-get install rlwrap
# CodeConsole='rlwrap -aAcN /opt/dsf/bin/CodeConsole'
# CodeConsole

Now you'll have use of the arrow keys to repeat a previous command or edit one and the history saves across executions.

Nice tweak

Oh IO redirection works as well now, e.g. echo M115 | /opt/dsf/bin/CodeConsole
