Q. Why the PDS/tDS does not transfer data from Ethernet to serial port?

 Ans: In some socket program written by user, they may face the problem that PDS/tDS can’t send or receive data properly.

In their program usually, they cut off the connection immediately after sending the data to our PDS/tDS. This method looks fine, but actually could bring an abnormal result. That’s because the PDS/tDS can flush the data in buffer when receiving a disconnect packet. In other words, it lead to the PDS/tDS losing message.

To avoid the occurrence of this problem, please modify your socket program.
For example, add a “delay function” between “data send” and “socket disconnection”.
