The above example already includes serial connections. Once the cable is connected and heartbeat started, you may tap into heartbeat's data by catting /dev/ttyS0 (or whatevery connections you're on)
cat If you need to test your serial connection, run the above on the recipient and then run the following on the sending machine:
echo hello >/dev/ttyS0
