FX30S listen to TCP port and direct to ttyHSL0

Looking for the best way to listen to a TCP port and direct data to the DB9 /dev/ttyHSL0

Options I have looked at:
busybox netcat (nc) (not compiled to listen to tcp ports)
socat (doesn’t exist)
python (would need to compile? several modules which aren’t available such as “socket” and “serial”)

It seems like there should be an easier or already existing legato program or method
Any hints would be great Thanks
