Test sending and receiving a string using interrupts.
This test sends one string from one USART to another. Both the send and receive is done using interrupts.

Test sending (blocking) and receiving (interrupt) a string.
This test sends one string from one USART to another. It's sent using a blocking write, while it's received using interrupts.
