Here are the built-in GP serial port functions:

-- Serial Port --
listSerialPorts
openSerialPort
isOpenSerialPort
closeSerialPort
readSerialPort
writeSerialPort

I got this by running the 'help' function in a workspace window. (To open a workspace, first enter developer mode, then select 'workspace...' from the stage menu.)

This gave me a long list of built-in functions. You can scroll down to find the serial port functions.

You can use the 'help' function with the name of a built-in function in a workspace like this:

That opens a new window that says what the function does:

A good way to learn about the serial port is to plug some device into the serial port and experiment with the serial port blocks.

I hope that helps!
