Documenting this issue for other people.

Issue: When using the included test, cannot write to the rp2040, instead raising error code 121 timeout error.

Details: Plugging in a raspberry pi pico and running the available test yields 121 timeout errors.

Solution: Enable DTR with my_serial.setDTR(DTR_CONTROL_ENABLE); after instantiation of my_serial.
