6.2.4 Read file procedure
Whether to read file data from the device to the local, or read the file from the FTP server
data to local, in addition to differences in the command format, the same process has been
followed. First of all, to open the file, and then read from a data file, in order to distinguish
between the data blocks, the read file data command must carry the serial number of data blocks,
if failed to read, the same piece of data can be read again, prevent the loss of data blocks; close the
file when finish, otherwise an error will occur when read and write documents again.
