SATO CL6NX - TCP Connection Queue

TCP connection queue
TCP connection queue functionality allows the printer to return an acknowledgement response
(ACK) to a connection request (SYN) from another host while the printer is connected to one host.
Note: For connection with one host, this function prevents the printer from returning a forced
disconnection (RST) to the host if the printer receives the next connection request (SYN) ahead in
case a process of connection termination (FIN) is delayed by network delay.
TCP connection queue: Disabled
While connected to one host, the printer returns a forced disconnection (RST) to a connection
request (SYN) from another host.
