Attached you'll find a code fragment as example. Configure your serial port as required. Read responses etc.
The example just uses a for loop to send one string out of an array of
strings to the specified port. Inside the loop, there's a
wait_until_next_multiple_ms node, which ensures the regular sendings
(with respect to the OS's possibilities, of course).
