Description
sending the next data.
Enable or disable queue access mode. The options are:
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.
How long to allow the serial server to respond to each host's
request, the specified time after the arrival of the serial
server and the host that the communication is complete,
continue 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.
