The transmission from the host computer proceeds as follows.
1. The ENQ code is sent from the host computer to establish a data link.
2. After the data link is established, the data is sent from the host
computer. The data transmission should be completed in a single
block.
3. After the request to send is accepted, the host computer should be
ready to receive.
The DX100 sends the ENQ code to establish the data link.
4. After the data link is established, the data sent from the DX100 is
received to terminate the transmission at completion of receipt.
The read/write function can be distinguished by the header number.
Refer to the header number list.
