NPort 6000 Series
Configuring Serial Port Operation Modes
7-26
LPD PRN Mode
TCP alive check time (default=7 min): This field specifies how long the NPort 6000 will wait for a response
to “keep alive” packets before closing the TCP connection. The NPort 6000 checks connection status by sending
periodic “keep alive” packets. If the remote host does not respond to the packet within the time specified in this
field, the NPort 6000 will force the existing TCP connection to close. For socket and device control modes, the
NPort 6000 will listen for another TCP connection from another host after closing the connection. If TCP alive
check time is set to 0, the TCP connection will remain open even if there is no response to the “keep alive”
packets.
Queue name (RAW): This field optionally specifies the print queue’s name (in RAW mode)
Queue name (ASCII): This field optionally specifies the print queue’s name (in ASCII mode)
Append from feed (default=Disable): This field instructs the port to send a line feed in between print jobs,
rather than continue where the last print job left off. This may be necessary for some applications.
