Flush Buffer
This option determines whether when a network-side connec-
tion is opened to the Com-Server the serial receive buffer is
cleared (Flush Buffer = 1) or any existing data are sent to the
client application (Flush Buffer = 0). Details can be found in
the section Basic configuration of the Com-Server.

When sending serial protocols such as Modbus/RTU, it is of-
ten necessary to send serial received datagrams also closed
on the network side in a TCP packet. The menu paths shown
above offer various ways to parameterize serial packet limits
(pause times, start-/end sequences, datagram lengths) and to
activate their processing for the respective mode. Details can
be found in the section Packeting of serial datagrams.
