Yes, they do. The commands are in the scripting online manual. Works great. The UART port receives and only certain Digital ports. Also look in the specs for which ports.

• D5 (TX) and D6 (RX) can be used as UART1 with 5kB Receive buffer
• D18 (TX) and D19 (RX) can be used as UART2 with 5kB Receive buffer

UARTInit( boardIndex, port, baudRate ) Initialize the Peripheral UART on the EZ-B v4 with the specified baud rate. The Board Index is the EZ-B index starting at 0. The port can be 0, 1 or 2. The baud rate can be between 1 and 3750000 bps. The UART receive buffers on the EZ-B v4 are 5,000 bytes. Example: UARTInit(0, 0, 9600 )

UARTAvailable( boardIndex, port ) Receive the count of bytes available in the Peripheral UART Receive Buffer of the EZ-B v4. The UART receive buffers on the EZ-B v4 are 5,000 bytes. The Board Index is the EZ-B index starting at 0. The port can be 0, 1 or 2. Example: UARTAvailable(0, 0)

UARTRead( boardIndex, port, numBytes ) Receive the bytes from the Peripheral UART Receive Buffer of the EZ-B v4. The UART receive buffers on the EZ-B v4 are 5,000 bytes. To know how many bytes are available, use the UARTAvailable() function. The Board Index is the EZ-B index starting at 0. The port can be 0, 1 or 2. Example: UARTRead(0, 0, 10) Example: UARTRead(0, 0, UARTAvailable(0, 1))

UARTWrite( boardIndex, port, data ) Write data through the Peripheral UART. The Board Index is the EZ-B index starting at 0. The port can be 0, 1 or 2. Example: UARTWrite(0, 0, hello world ) Example: UARTWrite(0, 0, 0x30, 0x40, hello )

There's also a good project example in the cloud you can download to see how it works. Look for the UART example.

In addition to Dave's reply, this is the V4 only. The V3 doesn't have the capabilities to receive serial data.

Excellent! Thanks guys!
