Sharing a Real Port Among Several Apps
To share one real port among multiple applications, perform the following steps:
1. Select a real port for sharing.
2. Choose applications that will get shared access to the port and set their custom rights. To do this, specify the full path to each application and click the “Set custom rights” button.
3. Set the access rights by toggling “Read”, “Write”, and “Control” options for each app.
Note: Only one application can manage serial port’s control lines and change the states of control line signals (RTS\DCD\etc). That means the controlling app can connect to a shared serial port multiple times. For instance, if you have granted Windows HyperTerminal with managing rights, you can launch it several times and each instance of HyperTerminal can be connected to a shared serial port without any problems. However, only the first instance will have access rights to manage the control lines. In most cases, allowing reading (“Read”) and writing (“Write”) are enough to access a shared serial port.
4. In case you modify access rights, click “Set custom rights” to apply changes.
5. Note: when sharing a real port between several applications, ports on both sides of a connection are the main ones.
6. Now, click the “Add share” button to create a bundle. The bundle will automatically appear in the Bundle tree.
Note: If you receive an error message when creating a port bundle, you can analyze the information shown in the Activity log.
