COD and U2S as shown in the table below 26 Parameter change Comm Connection S W s Protocol through the serial Topology Mode Type Modification port TCP is a protocol that requires a connection process Connection always takes place a one to one basis A host waiting for connection passive connection is called a server and one attempting to make a connection active connection is called a client On the other hand UDP communicates by the block without the process of connection and thus allows multiple hosts to communicate simultaneously e For detailed operation modes refer to the next chapter a Os 5 NORMAL COMMUNICATION MODES zl T2S TCP to Serial In T2S mode the ezTCP functions as a server When a TCP connection comes from a remote host to the predefined local port the ezTCP accepts a TCP connection When the ezTCP accepts TCP connection then the TCP connection is established After connection is established TCP IP processing is performed on the data coming to the serial port which is then transmitted to the remote host And the TCP IP data coming from the remote host is TCP IP processed and transmitted to the serial port to establish data communication Data coming to the serial port before TCP connection is established will be ignored In T2S mode the ezTCP functions as a server Therefore T2S mode cannot be used in a dynamic IP environment DHCP Remote Host ezTCP Serial Device L2.
