NAME

cons − VAX-11 console interface

DESCRIPTION

The console is available to the processor through the console registers.  It acts like a normal terminal, except that when the local functions are not disabled, control-P puts the console in local console mode (where the prompt is “>>>”).  The operation of the console in this mode varies slightly per-processor. 

On an 11/780 you can return to the conversational mode using the command “se t p” if the processor is still running or “continue” if it is halted.  The latter command may be abbreviated “c”.  If you hit the break key on the console, then the console will go into ODT (console debugger mode).  Hit a “P” (upper-case letter p) to get out of this mode. 

On an 11/750 the processor is halted whenever the console is not in conversational mode, and typing “C” returns to conversational mode.  When in console mode on an 11/750 which has a remote diagnosis module, a ^D will put you in remote diagnosis mode, where the prompt will be “RDM>”.  The command “ret” will return from remote diagnosis mode to local console mode. 

With the above proviso’s the console works like any other UNIX terminal.
