. SerialTunnel is the “server side” component used to support tunneling of Windows serial-connected PC applications to devices
reachable in a station’s driver network. Typically, serial tunneling is used with a “legacy” vendor-specific PC program to
access RS-232 connected devices attached to a JACE controller.
You can add one or more SerialTunnels under a station’s TunnelService. Each SerialTunnel associates with one specific driver network (and corresponding JACE serial port). See Serial tunneling for more details.
Properties of the SerialTunnel are described as follows:
-
Enabled
Boolean slot that must be enabled (true) to permit tunneling.
-
Connections
Read-only slot to indicate the number of tunnel connections, as either 0 (none) or 1 (maximum).
-
Status
Read-only status of the serial tunnel, typically
ok(unlessfaultfor no supporting COM port). -
Identifier
Read-only “reflection” of the entered Port Name slot in the Serial Port Config container (below), used as the “Tunnel Name” when configuring the client-side Serial Tunneling dialog.
-
Serial Port Config (container)
Holds configuration of the JACE serial port as used by the specific driver network. See SerialHelper for slot descriptions.
In addition, a SerialTunnel has an available (right-click) action:
-
Disconnect All
Disconnects any active connection through this SerialTunnel (maximum of 1), causing removal of the “TunnelConnection” below it. On the remote (serial tunnel client) side, a popup message “Connection closed by remote host” is seen.
Any TunnelConnection component also has its own “Disconnect” action, which effectively performs the same function.
