Socat tcp-l:54321,reuseaddr,fork file:/dev/ttyS0,nonblock,waitlock=/ var/run/ttyS0.lock How to test it: program the rootfs to a standard build kernel (with JFFS2 rootfs support) to the modules partitions. Make sure to have those libraries into your rootfs. Socat requires libraries: librt, libssl, libpthread.
