network connections.


response is lost, the system will wait until the data is
successfully sent to all network connections before
sending the next data.
Enable or disable queue access mode. Options:
Enabled: Multiple hosts can send or receive data from

the serial port at the same time. The serial server
processes the communication data in the order of FIFO
(first in, first out), prioritizes requests from the first host,
and returns the response to the first host.
Disabled: Means that queue access mode is not

enabled.
Time interval that allows the serial server to respond to each
host's request, the communication between serial server and
host is deemed to be completed after schedule time, serial
server continues to deal with the next host request.
If the idle wait time after the serial and host communication is
completed is longer than the frame break setting time, the
serial port will consider the communication to be completed
and continue processing the command from the next host.
This approach is very effective in reducing latency and
improving product performance.
Check the "Apply to all port" check box to apply the current
settings to all serial ports.
