To share one real port among multiple applications, follow these steps:

  1. Сreate a new port bundle. To do that, click the “Share” icon on the vertical menu at the left, then click the “Share port” button:

2. Select a real port you want to share from a drop-down list and use the button to access its settings if needed. Then add the apps that will get shared access to this port by clicking the “+” button (to remove an app from the list, click the “-” button). For each app, you can set custom rights (Read, Write, and Control) using the respective checkboxes.

Also, you can enter a custom name for this bundle into the “Description” field for easier identification:

Note: Only one app at a time can manage serial port’s control lines and change the states of control line signals (RTS\DCD\etc). However, the controlling app can connect to a shared serial port multiple times.

For instance, if you’ve ticked the “Control” checkbox for Terminal, you can launch it several times and every instance won’t have any problems connecting the shared serial port, but only the first instance will have access rights to manage the control lines. In most cases, to access a shared serial port it’s enough to have just “Read” and “Write” rights.

     3. Click the “Create” button. Now you can click this port bundle in the Bundle tree to view its settings:

Note: If you receive an error message when creating a port bundle, you can analyze the information shown in the Activity log.
