Communication through the USART-to-USB gateway

The Atmel ATmega1284P USART is connected to an USART on the Atmel AT32UC3B1256. The Atmel ATmega1284P USART is communicating at 57600 baud, using one start bit, eight data bits, one stop bit and no parity.

When the Atmel AT32UC3B1256 device is enumerated (connected to a PC) the data transmitted from the Atmel ATmega1284P is passed on to a (virtual) COM port. This means that it is possible to use a terminal program to receive the transmitted data on a PC. Similarly data transmitted from the PC COM port is passed on to the Atmel ATmega1284P USART through the gateway.
