- Launch “Shared Serial Ports” application if it is not started yet. The default path to it: “Start” -> “All programs” -> “Eltima Software” -> “Shared Serial Ports” -> “Configure Shared Serial Ports”.
- In Serial ports tree select serial port you want to modify access rights for.
- In “Add application with custom access rights” text field of Configuration panel specify the full path to the application you want to set custom access rights for:
- Check/uncheck “Allow reading”, “Allow writing” and “Manage control lines” boxes. This will grant or restrict certain access parameters to shared serial port for the chosen application.
Note, that only one application can manage serial port’s control lines. It is the only application which is able to change control line signals’ states (RTS\DCD\etc.) and, as the result, have full access to serial port device. In fact, control lines’ managing application can establish connection to shared serial port as many times as you like. For instance, if you have granted Windows HyperTerminal managing rights, you can launch it several times and each instance of HyperTerminal can be connected to shared serial port without any problems. However, only the first instance will have access rights to manage the control lines.
In most cases, “Allow reading” and “Allow writing” options are enough to access shared serial ports.
- Click “Set custom rights” button to apply access rights.
Important notice: Restart the application after changing the access rights for it.
