 Remote Node Programming
In this example, programming is also required in the remote node. The order of sending and receiv-
ing is reversed in comparison with the above procedure.
1
The SktTCPAccept instruction is executed to request accepting a TCP socket.
2
The SktTCPRcv instruction is executed to request receiving data. The receive data is stored in
RcvSocketDat[].
3
The SktTCPSend instruction is executed to request sending data. The data in SendSocketDat[]
is sent.
4
The SktClose instruction is executed to close the socket.
