Tunnel Accept Mode
Settings
Description
Mode Set the method used to start a tunnel in Accept mode. Choices are:
Disable = do not accept an incoming connection.
Always = accept an incoming connection (default).
Any Character = start waiting for an incoming connection when any
character is read on the serial line.
Start Character = start waiting for an incoming connection when the
start character for the selected tunnel is read on the serial line.
Modem Control Asserted = start waiting for an incoming connection as
long as the Modem Control pin (DSR) is asserted on the serial line until
a connection is made.
Modem Emulation = start waiting for an incoming connection when
triggered by modem emulation AT commands. Connect mode must
also be set to Modem Emulation.
Local Port Set the port number for use as the network local port. The default local port
number for each supported serial line number progresses sequentially in
equal value so that Tunnel X : 1000X. For example:
Tunnel 1 : 10001
Tunnel 2 : 10002
Protocol Select the protocol type for use with Accept Mode:
TCP (default protocol)
TCP AES
Telnet
TCP Keep Alive Enter the time, in milliseconds, the XPort Pro Lx6 waits during a silent TCP
connection before checking if the currently connected network device is
still on the network. If the unit gets no response after 1 attempt, it drops
the connection. Enter 0 to disable.
Flush Serial Set whether the serial line data buffer is flushed upon a new network
connection. Choices are:
Enabled = serial data buffer is flushed on network connection
Disabled = serial data buffer is not flushed on network connection
(default)
Block Serial Set whether Block Serial is enabled for debugging purposes. Choices are:
Enabled = if Enabled, incoming characters from the serial line will not
be forwarded to the network. Instead, they will be buffered and will
eventually flow off the serial line if hardware or software flow control is
configured.
Disabled = this is the default setting; incoming characters from the
Serial Line are sent on into the network. Any buffered characters are
sent first.
Block Network Set whether Block Network is enabled for debugging purposes. Choices
are:
Enabled = if Enabled, incoming characters from the network will not be
forwarded to the Serial Line. Instead, they will be buffered and will
eventually flow off the network side.
Disabled = this is the default setting; incoming characters from the
network are sent on into the Serial Line. Any buffered characters are
sent first.
