Keepalive
Check
Time
0
After a certain amount of time passes without any communication
after the socket connection between the given serial port and the
server is established, automatically disconnect the socket
connection. Valid from 0 to 32767 sec.
For example, if the operation mode is set to TCP Server and Alive
Check Time is configured to 10, TCP Server will listen for the client ’s
connection and eventually establish a connection. Since the check
time is 10 seconds, the server will wait for 10 seconds until the client
connected to it sends any packet. If there is no data for 10 seconds,
server will quit the connection and return to the listening state. This
option is helpful in preventing communication obstacles that occur
when either SerialGate or the client quits unexpectedly (i.e. Sudden
black out, reboot, LAN cable cut, etc.). In these cases, the other part
of communication might not recognize the failure of its partner. Such
misunderstanding can cause communication errors.
If the value is set to 0, this function is disabled. Once connected
socket will be retained until explicitly disconnected.
(Only applies to TCP Client, TCP Server, TCP Broadcast, and TCP
Multiplex operation modes.)
Latency
Time
0
This needs to be set when consecutive data from the given serial
port needs to be transmitted to socket at once.
For example, if 100 bytes of character string are to be transmitted
from the serial device to a server through SerialGate, bypass is set to
0 for the latency time. Although it provides immediate sending
through SerialGate, the server could be received a lot parts of
divided packets.
If the latency time is not 0, SerialGate will wait for the time and check
new data. If there is new data, SerialGate repeatedly wait for the
time. Otherwise, SerialGate will transfer the buffered data, but it
could not run in real time.

When operating with TCP Multiplex mode, the SerialGate sends a
data to the device and waits given amount of time. When there are
