7-3
Auxiliary Area and CIO Area Allocations
This section describes the bits and words used by the Serial Communications
Board and Serial Communications Units in the Auxiliary Area and the Status
Area and Software Switches allocated in the CIO Area used for no-protocol
communications.
Auxiliary Area Allocations
Port 1 and Port 2 Port Settings Change Bits
These bits can be turned ON from the program using the OUT or other
instructions to change communications settings and restart the serial port.
When changing the settings and restarting the port have been completed, the
bit will automatically be turned OFF.
Note
These bits are used both to change the port settings and to restart the port at
the same time. One of these bits can be turned ON to restart a port without
changing the port settings in the Setup Area allocated in the DM Area. The
STUP(237) instruction can also be used to just restart a communications port
by executing STUP(237) with the same port settings as the ones already
being used.
