CDC.getKey

Name
CDC.getKey - get character from CDC device

Description
This command fetches a character from the keyboard buffer.

The Communication Device Class (CDC) is a general-purpose way to enable all types of communications on the Universal Serial Bus (USB). This class makes it possible to connect communication devices such as digital telephones or analog modems, as well as networking devices like Asymmetric Digital Subscriber Line (ADSL, DSL) or Cable modems. While a CDC device enables the implementation of quite complex devices, it can also be used as a very simple method for communication on the USB. For example, a CDC device can appear as a virtual COM port (terminal window), which greatly simplifies application development on the host side.
