Remarks:
After Start Input is ON, the PC transfers the data from DM 0101 onward based on
the contents of DM 0100 as the data length. From word 2 on, the data is trans-
ferred whenever the ASCII write complete instruction is ON.
When data transfer starts, 00115 is turned ON and when data transfer is com-
pleted, 00115 is turned OFF to inform the ASCII Unit of data transfer and
completion.
