# \brief  Test for the Noux terminal file system
# \author Christian Prochaska
# \date   2012-06-11
#

#
# The test shows two framebuffer terminals. The upper terminal runs an
# interatctive shell and the lower terminal can be accessed from the shell via
# /dev/terminal.
#
# Example for writing to the lower terminal: echo "test" > /dev/terminal
# Example for reading a line from the lower terminal: head -n 1 /dev/terminal
#
