The display cpu=@ command does not work
on UNIX™
In UNIX™, nothing happens when typing display cpu=@ at the composer prompt.
Cause and solution:
The @ (atsign) key is set up as the "kill" character.
Type stty -a at the UNIX™ prompt
to determine the setting of the @ key. If it is set as the "kill"
character, then use the following command to change the setting to
be "control/U" or something else:
stty kill ^U
