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