configitem Protocol
value
The Protocol used on the connection can be TCP.
Protocol may be "TCP".
configitem Start Character
value
When the Start Character is received on the Serial Line, it enables the tunnel to listen for a network
connection.
The Start Character may be designated as a single printable character or as a control character.
Control characters may be input in any of the following forms:
<control>J
0xA (hexadecimal)
\10 (decimal)
Start Character may contain one character, where <control>J, for example, counts as one.
configitem Flush Start Character
value
Enabling Flush Start Character prevents forwarding of a start character from the Line into the network.
Disabling Flush Start Character allows forwarding of a start character from the Line into the network.
Flush Start Character may be "Enabled" or "Disabled".
configitem Flush Line
value
Flush Line applies at the time when a connection is accepted from the network.
If Enabled, any buffered characters from the Serial Line will be discarded when a connection is accepted.
If Disabled, any characters received on the Serial Line will be buffered and sent after a connection is
accepted.
Flush Line may be "Enabled" or "Disabled".
configitem Block Line
value
Block Line may be enabled for debugging purposes.
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.
If Disabled (the normal setting), incoming characters from the Serial Line are sent on into the network.
Any buffered characters are sent first.
Block Line may be "Enabled" or "Disabled".
