U2S
U2S mode allows for UDP communication.
In UDP mode, data are transmitted in blocks, which requires dividing data coming to the
serial port into blocks before transmitting data. A procedure for dividing data into
blocks is as follows:
If data of pre-specified bytes [Conn. Byte] comes to the serial port of the ezTCP or if a
specified period of time [TIMEOUT] elapses after first data reception, all data received
for the same period is recognized as one block which is then transmitted to the
UDP. The [TIMEOUT] unit is 10ms. If [TIMEOUT] is set to 2, the time period is
between 20ms and 30ms.
Since UDP communication does not require a connection procedure, the user can
establish N-to-M communication via multicast and broadcast.
