8. Operating Mode:
Three different Socket Modes and one real COM modes are available:
TCP Server, TCP Client, and UDP Server/Client. The main difference
between the TCP and UDP protocols is that TCP guarantees delivery of
data by requiring the recipient to send an acknowledgement to the sender.
UDP does not require this type of verification, making it possible to offer
speedier delivery. UDP also allows multicasting of data to groups of IP
addresses.
