                     11: .SH DESCRIPTION
                     12: The console is available to the processor through the console registers.
                     13: It acts like a normal terminal, except that when the local functions are
                     14: not disabled, control-P puts the console in local console mode (where
                     15: the prompt is ``>>>'').  The operation of the console in this mode varies
                     16: slightly per-processor.
                     17: .PP
                     18: On an 11/780 or 785
                     19: the processor is not stopped by entering local console mode.
                     20: The CPU may be halted with the ``halt'' command, which may be abbreviated
                     21: to ``h.''
                     22: Conversational mode is re-entered by using the command
                     23: ``set t p'' (set terminal program) if the processor is still
                     24: running, or ``continue'' if it is halted.
                     25: The latter command may be abbreviated ``c''.
                     26: If you hit the break key on the console, then the console LSI-11
                     27: will go into ODT
                     28: (console debugger mode).  Hit a ``P'' (upper-case letter p; ``proceed'')
                     29: to get out of this mode.
                     30: .PP
                     31: On an 11/750
                     32: or an 11/730
                     33: the processor is halted whenever the console is not in conversational mode,
                     34: and typing ``C'' returns to conversational mode.
                     35: When in console mode on an 11/750 which has a remote diagnosis module,
                     36: a ^D will put you in remote diagnosis mode, where the prompt will be ``RDM>''.
                     37: The command ``ret'' will return from remote diagnosis mode to local console
                     38: mode.
                     39: .PP
                     40: The VAX 8600 (8650) console normally works in the same way as the 11/750,
                     41: except that there are many additional modes and commands.
                     42: In the normal mode
                     43: control-P halts the processor, and ``c'' or ``continue'' returns to
                     44: conversational mode.
                     45: If HEX debug is enabled, control-P does not halt the CPU; the ``halt''
                     46: command stops the CPU as on the 11/780.
                     47: .PP
                     48: With the above proviso's the console works like any other UNIX terminal.
