File Upload Protocol Example
The protocol (Figure 2 and Figure 32) for uploading a dynamic data file begins with the
client application sending the
Open DataPort
command through the instrument's
Control Port. Upon receiving acknowledgment back through the Control Port, the
client application opens and connects to the Data Port of the instrument. Upon
successfully connecting to the Data Port, the client application then sends the
Begin
File Uptransfer
command through the instrument's Control Port. Upon
receiving an acknowledgment back through the Control Port, the client application
sends the command
Next File Uptransfer
through the Control port which will
generate a response of a binary data segment through the instrument's Data Port. After
the last segment has been received through the Data Port, the client application sends
the
End File Uptransfer
command through the Control Port. Once the
acknowledgment is received through the Control Port, another file transfer may begin.
After all files have been uploaded, the client application sends the
Close DataPort
command through the Control Port. Upon receiving acknowledgment back through the
Control Port, the client application must close the data port connection.
