* \section Sec_Compat Project Compatibility:
*
* The following list indicates what microcontrollers are compatible with this project.
*
* \li Series 7 USB AVRs (AT90USBxxx7)
* \li Series 6 USB AVRs (AT90USBxxx6)
* \li Series 4 USB AVRs (ATMEGAxxU4)
* \li Series 2 USB AVRs (AT90USBxx2, ATMEGAxxU2)
*
* \section Sec_Info USB Information:
*
* The following table gives a rundown of the USB utilization of this project.
*
* <table>
* <tr>
* <td><b>USB Mode:</b></td>
* <td>Device</td>
* </tr>
* <tr>
* <td><b>USB Class:</b></td>
* <td>Communications Device Class (CDC)</td>
* </tr>
* <tr>
* <td><b>USB Subclass:</b></td>
* <td>Abstract Control Model (ACM)</td>
* </tr>
* <tr>
* <td><b>Relevant Standards:</b></td>
* <td>USBIF CDC Class Standard</td>

* <tr>
* <td><b>Supported USB Speeds:</b></td>
* <td>Full Speed Mode</td>

*
* \section Sec_Description Project Description:
*
* USB to Serial bridge project. This project allows a USB AVR to serve
* as a USB to USART bridge between a USB host and a device lacking a
* USB port. When programmed into a USB AVR, the AVR will enumerate as a
* virtual COM port.
*
* The AVR's hardware USART's settings will change to mirror as closely as
* possible the serial settings set on the host. However, due to hardware
* limitations, some options may not be supported (baud rates with unacceptable
* error rates at the AVR's clock speed, data lengths other than 6, 7 or 8 bits,
* 1.5 stop bits, parity other than none, even or odd).
*
* After running this project for the first time on a new computer,
* you will need to supply the .INF file located in this project
* project's directory as the device's driver when running under
* Windows. This will enable Windows to use its inbuilt CDC drivers,
* negating the need for custom drivers for the device. Other
* Operating Systems should automatically use their own inbuilt
* CDC-ACM drivers.
*
* \section Sec_Options Project Options
*
* The following defines can be found in this project, which can control the project behaviour when defined, or changed in value.
*
* <table>
* <tr>
* <td>
* None
* </td>
