+# Use a container to implement a serial to net bridge
+
+This uses `ncat` by [namp](https://nmap.org/ncat/) to bridge a serial port to a network port. The serial port is passed to the Podman command (eg. `/dev/ttyUSB0`) and the network port is `2560`.
+
+> [!IMPORTANT]
+> Other variants of `nc` or `ncat` may not work as expected.
+
+## Build and run the container
+
+```bash
+$ podman buil -t dcc/bridge .
+$ podman run -d --device=/dev/ttyUSB0:/dev/arduino -p 2560:2560 --name dcc-bridge dcc/bridge
+```
+
+It can be tested with `telnet`:
+
+```bash
+$ telnet localhost 2560
+```
