The "size of file" parameter is used for limiting the file size of the csv file. All the input from 
serial port will be saved in the .csv file, and once the file size of that csv file exceed the 
size limit, another file will be created to hold the input. The value allowed is 1000 - 
100*1000 Bytes. 
Based on the configuration, the file could be uploaded to server periodically. For 
example, 
AT$$FTPCS=5,192.168.10.50:21, maxon, maxon, 30,FILEHEADER,10000,0 
with this setting, the modem will send out .csv file to FTP server every 30 minutes. If the 
input has not exceeded limit 10K bytes (in this case), modem will send this file only, then 
generate another file for holding future input. If the input is more than 10K bytes, there 
should be more than one file generated, each file should not exceed 10K bytes, all these 
files will be sent to FTP server when time comes.
