terminal port
Connects the console terminal to the system.
Console program Software interface; translates console commands to the proces-
sors; resides in ROM on each processor.
Dedicated memory The console communications area (CCA) in main memory that al-
lows the console programs on each processor to communi-
cate with each other.
In multiprocessor systems, the console program runs on all processors,
and the console program on the primary processor communicates with
the console terminal (see Section 4.5). Each processor communicates with
the others through a segment of shared main memory called the console
communications area (CCA).
To use the console terminal in console mode, set the upper key switch on
the control panel to the Enable position. The lower key switch can be at
Update or Halt. The control panel is described in Chapter 3.
You designate a terminal as the console terminal by connecting it to the
console terminal port. The console terminal port connection is on the I/O
distribution panel above the AC power controller (see Section 2.4). The
default console baud rate is 1200 when a system is installed. See the SET
TERMINAL command for instructions on changing the defaults. The break
key can also be used to change the baud rate (see Section 5.4).
When the system is in console mode, the terminal has exclusive use of the
system.
