It is necessary create a program at the host computer to receive the data and
send a response.
When CIO 0.00 and A202.07 (the Communications Port Enabled Flag for port
07) are ON in the following example, the ten words from D100 to D109 are
transmitted to node number 3 in the local network where they are written to
the ten words from D200 to D209. The data will be retransmitted up to 3 times
if a response is not received within ten seconds.
