1. If the LS100 sends a connection request to a remote host the state is changed from Closed to Sync Sent This state is maintained until the remote host accepts the connection request This state is valid only in TCP client mode Established represents an open connection one of the hosts accepts a connection request from the other host the connection is opened and state is changed into Established Data When it is in Established state data from a host will be transferred to the other one For easier understanding of the TCP session operation we called the state as Data state when actual data transfer is performed Actually the Data mode is a part of Established state as is described in the RFC 793 Transmission Control Protocol This is a normal state for the data transfer phase of the connection 4 1 TCP Server Mode Operations 4 1 1 Overview The LS100 works as a TCP server and the default TCP state is Listen in this mode The LS100 supports only one TCP socket connection per one serial port If a connection is currently established the additional connection requests will be rejected The remote host will be either Ethernet Serial communication devices acting as a TCP client or a socket program acting as a TCP client running on users PC 1 Typical State Transition Listen gt Sync Received gt Established gt Data gt Closed Listen At start up an2.
