5.1 File Data Transmission Function
The transmission from the DX100 to a host computer proceeds as follows.
DX100 → Host computer
1. The ENQ is sent from the host computer to establish a data link.
2. After the data link is established, a request to send is sent from the
host computer.
3. The request to send consists of a header number and a subcode
number. Refer to the header number list.
4. After the request to send is accepted, the host computer should get
ready to receive data.
The DX100 sends the ENQ code to establish a data link.
5. After the data link is established, receive the data sent from the
DX100. The transmission terminates at completion of reception.
If the data requested to send are not found, or the header of the
request to send has an error, the DX100 sends the following response
message instead of data.
