(c) Sample program

*1

There are two kinds of TCP receive modes: TCP standard receive mode and TCP fixed-length receive mode.
For fixing the data size, run the program enclosed by a dotted line. (It can be omitted when the data size is not fixed.)

For the TCP receive mode, refer to the section for the SP.SOCRMODE instruction. (

 Page 129, Section 7.4.8)

*2

For acquiring information of the device connected on TCP, run the program enclosed by a dotted line. (It can be omitted 
when the information acquisition is not needed.)
