You'll need to integrate with some external code.
Integration options depend on the tier (client/server) from which access is required, and on the code/API currently available to access the device.
If access is from the server side, than you could either call a standalone executable via Miscellaneous/Run External Command (here's a thread on the subject), or create a new Tersus plug-in (see here).
If you require access directly from the client, you'll probably need to create/use a java applet (via Display Actions/Call Java Applet).
For best results, use the Firefox browser..
