Not necessarily.
That checks RX/TX only.
The link will usually work with incorrect handshake if data rate is
slow.
It is vital on links to 'real' QLs that handshake is correctly
connected. You _might_ get away with it on fast hardware with good
serial chips - like 16550 (PN from memory).
Often one finds RTS is not connected at all!
