 Normally, data received from UART are sent to Ethernet immediately. But in many cases, users want to send data as a
 chunk of the whole frame without separated ones. This option is for packetizing data into one frame.
 
-    Time (0 ~ 65535 ms, ‘0’: Function Disable) : 
-        This field is for specifying time value (in ms) to judge whether one frame 
-        is received totally. If the time specified in this field is expired 
-        after receiving one byte, then WIZ550S2E notice one data frame is finished, 
-        make an Ethernet packet with all data in its serial buffer and send it to 
-        the peer system via Ethernet. 
-        If WIZ550S2E receives another byte from UART before the specified time is expired, 
-        it restart timer and add the received one to the end of serial data buffer.
-    Size (0 ~ 255 byte, ‘0’: Function Disable) : 
-        This field is for specifying size value to judge whether one frame is 
-        received totally. If the size specified in this field is received, then WIZ550S2E 
-        notice one data frame is finished, make an Ethernet packet with specifying size's

-        This field is for specifying delimiter value to judge whether one frame is 
-        received totally. Char delimiters can be set up to 4 bytes in HEX and valid 
-        character count is decided according to the value in Length field. In case the 
-        value of Length field is '0', this option becomes inactivated. 
-        Appendix is another option for this. If user selects any value in Appendix field,
