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 Com-
munications Unit ports. When changing the settings and restarting the port
have been completed, the bit will automatically be turned OFF. The port 1 or
port 2 Port Settings Change Bits and Restart Bits are allocated in the Auxiliary
Area according to the unit number as shown below.
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.
