It is shown in case that CONNECT commands are given to
Socket n Command Register(Sn_CR) at the SOCK_INIT status.
It is automatically changed to SOCK_ESTABLISH when the
It is shown in case that Sn_MR is set as TCP and OPEN
commands are given to Sn_CR. This is the initial step for
TCP connection establishment of a socket. In this SOCK_INIT
status, the command type (LISTEN or CONNECT) of Sn_CR
will decide the operation type – TCP server mode or Client
mode.
It is shown in case that LISTEN commands are given to
Sn_CR at the SOCK_INIT status. The related socket will
operate as TCP Server mode, and become ESTBLISHED status
if connection request is normally received.
It is shown in case that connection is established. In this
status, TCP data is transmitted and received.
It is shown in case that connection termination request is
received
message has been received from the peer, but not
disconnected. The connection can be closed by receiving
the DICON or CLOSE commands.
It is shown in case that OPEN commands are given to Sn_CR
when Sn_MR is set as UDP . As this status does not need the
connection process with peer, the data can be directly
transmitted and received.
It is shown in case that OPEN commands are given to Sn_CR
when Sn_MR is set as IPRAW. At the IPRAW status, the
following protocols of IP Header are not processed. Refer to
“IP RAW” for more information.
It is shown in case that OPEN commands are given to S0_CR
when S0_MR is set as MACRAW.
At the MAC RAW status, there is no protocol process for a
packet. For more information, refer to “MAC RAW”.
It is shown in case that OPEN commands are given to S0_CR
when S0_MR is set as PPPoE.
