When I first started administering HP-UX systems, the first time I saw the following I wondered how the heck I was supposed to execute the key format. For the benefit of others (Note: Ignore case of the letters):
[Read only - use Ctrl-Ecf for console write access.]
^Ecf====Force control of the console interface.
To execute the ^Ecf command complete the following steps:
1.Press the Cntrl key and the e key simultaneously.
2.Release the Cntrl key and the e key.
3.Press the c key.
4.Press the f key.
