The console is available to the processor through the console registers.
It acts like a normal terminal, except that a ``~
\b~'' is used to transfer
commands to the console processor when the front panel key switch is in
the ``foo'' or ``bar'' position. When the console processor is in con-
trol, a `#>' prompt is displayed. To continue execution after halting
the machine with `~h', use `r'.
~
\b~h
\bh Halt the machine.
~
\b~r
\br Continue execution after a ~
\b~h
\bh.
Refer to the Tahoe console processor handbook for the complete list of
facilities available through the console processor.
The C

\bP device provides direct access to the console processor. The

it is normally connected to a modem.
