IOWR(223) writes the transmitting
device address, number of receiving
device addresses, and receiving device
address to buffer memory beginning at
memory address 0143 Hex.
Turns ON the Read Data Request Bit.
IORD(222) reads the data beginning at
buffer memory address 0154 Hex and
stores that data in the DM area
beginning at D02000.
Turns OFF the Read Data Request Bit if
the message was sent properly and the
Data Read Completed Flag was turned
ON.
Turns ON W200.00 if an error occurred.
