# What is a Device Driver?

Device drivers are connections between the device plug-in and Softimage that get and set the values or fire commands or events. A device driver contains a collection of channels and can implement a dialog box to configure the device, either through the user interface or the description file. For example, you need to set up the port number and baud rate for rs232 connection ports.
