Grant port access to applications

You can restrict access to created virtual serial ports for various applications.

At "Port access list" tab you can see the list of applications which you add via "Add mask" button:

Port access list

You can change priority for the selected applications by clicking Change priority and Down buttons.

You can delete masks by clicking  Delete and  Masks buttons.

Here is an example of restricting access to virtual serial ports for an application:

  1. Click one of the created virtual serial ports in Serial Ports Explorer and switch to "Port access list" tab.
  2. Click  Folder button, select the required application and click  Add mask
    button or enter full destination path to the required application manually.
  3. Now you can see your application in the table.
  4. Choose access rights status for the selected application: "denied" or "granted" in "Access" column.

Here are several examples of masks usage:

  1. All applications are forbidden to use the virtual port, except for Windows HyperTerminal: Windows HyperTerminal
  2. Only applications, located on local disc C, can use the virtual port: Using the virtual port
  3. All applications can use the virtual port, except for those, located on local disc C: Local disc C apps
  4. Only Windows HyperTerminal and Command Prompt can use the virtual port: Command Prompt
  5. Only applications, located in Program Files on local disc C can use the virtual port: Applications, located in Program Files
  6. Access will be granted to all applications, Windows HyperTerminal will not be forbidden: Windows HyperTerminal will not be forbidden

Note: Masks priority is ascending. This means that when the first match is met, further masks are ignored.
