Specify the timeout in seconds in the session_timeout field. It is important to specify the session_timeout if the FieldServer is mainly used as a serial protocol client continually communicating with the device. Under these circumstances, if a Telnet session captures the serial port, the protocol driver is put on hold until the port is released. -
Page 6: Using The Serial Port Capture
To release a port, the connected Telnet session must be disconnected. 2. Capturing a port makes the port unavailable to any protocol driver on the FieldServer that might have been communicating with the device. Refer to the comments on session_timeout above on how to prevent an indefinite lockout if a Telnet session with a port capture is forgotten on. -
Page 7: Autoconnect Serial Port Capture And Multiple Telnet Sessions
4.2. Autoconnect Serial Port Capture and Multiple Telnet Sessions If an autoconnect port has been specified, a new Telnet session to the FieldServer will automatically be connected to the specified port (in binary or text mode as specified). This raises a potential conflict if there is already an existing session autoconnected to that port. -
Page 8: Running Serial Protocols Over Telnet Using Virtual Ports
The Telnet driver will only capture ports that have been specified in the configuration file used by the FieldServer. It will use the specified port parameters (baud rate, start/data/stop bits, parity), or FieldServer defaults where these have not been specified.
