#define USE_DCD_REPORTING       0
/* If this option is defined to 1, the driver will report carrier detect when
 * the serial device is opened. This is useful on some Unix platforms to allow
 * using the /dev/tty* instead of /dev/cu* devices.
 * Setting this option to 0 saves a couple of bytes in flash and RAM memory.
 */
#define ENABLE_DEBUG_INTERFACE  1
/* If this option is defined to 1, the device buffers serial data (read from
 * the the ISP connector) and makes it available through vendor specific
 * requests to host based software. This is useful to display debug information
 * sent by the target.
 * Setting this option to 0 saves a couple of bytes in flash memory.
 */
#define ENABLE_HID_INTERFACE    1
/* If this option is defined to 1, the device implements a custom HID type
 * interface to send and receive STK500 serial data. If both, the CDC-ACM and
 * HID interface are enabled, a jumper selects which one is used.
 */
#define ENABLE_CDC_INTERFACE    1
/* If this option is defined to 1, the device implements a CDC-ACM modem,
 * emulating the behavior of the STK500 board on a virtual COM port.
 */
#define ENABLE_HVPROG           1
/* If this option is defined to 1, the high voltage programmer is enabled.
 */
#define HW_CDC_PACKET_SIZE      8
/* Size of bulk transfer packets. The standard demands 8 bytes, but we may
 * be better off with less. Try smaller values if the communication hangs.
 */
