Time out for receiving TCP data (Default: Disabled):
This field specifies how long the serial device
server will wait for a response to “keep alive” packets before closing the TCP connection. The serial device
server 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 serial device server will force the existing
TCP connection to close. If this setting is set to 0, the TCP connection will remain open even if there is no
response to the “keep alive” packets.
Character send interval (Default: Disabled)
This parameter defines how large a gap in character communication the serial device server will allow
before packing the serial data in its internal buffer for network transmission.
Serial to Network Packet Delimiter
Packet delimiter is a way of packing data in a serial communication. It is designed to keep packets in track.
Serial device server provides three patterns in parameter setting: (1)
packet delimiter by
(1)
Interval
timeout,
(2)
Max Byte
and (3)
Character pattern
.
1.
By Time
– The device will transmit the data when set time interval has reached and no more
data comes in.
2.
By Max Bytes
– The device will transmit the data when the data queue has reached the set
size.
3.
By Character
- The device will transmit the data when it sees the set character.
