I am trying to allow multiple users access to a serial device that cannot handle multiple users itself. How does the ConnectPort handle port sharing? Will it buffer communications to the serial device or does it just allow multiple connections but require the device or communications software to do traffic control?
The ConnectPort TS and TS MEI does NOT support sharing of the serial port in the way that the Portserver TS model did. In the context of your question, an application with an established socket connection to one of the CP-TS serial ports would need to “close” before any other application could make a connection to that device, i.e. requires devices to be their own traffic cop.
The serial port will block any attempts to connect to it if an application already is connected/has the port in use.
