•
For TCP sockets, the send data is resent up to 12 times if an acknowledgment (ACK) from the
remote node is not received. The resend interval increases to between one second and 64 seconds
for each resend.
•
For TCP sockets, a connection request (SYN) is sent by performing an open connection. SYN is
resent up to four time if an acknowledgment (SYN + ACK) from the remote node is not received. An
error will occur if SYN + ACK is not received even 75 seconds elapsed since the open processing is
performed.
