The serial terminal server ("serterm") is a collection of scripts that
automate launching multiple `picocom` processes, one per USB-serial
adapter connected to the system. Each `picocom` process has its own
window in a `tmux` session, which is accessible via SSH on a dedicated
port (20022). Clients connecting to that SSH server will be
automatically attached to the `tmux` session, allowing them to access
the serial terminal server quickly and easily. The SSH server only
allows public-key authentication, so the authorized keys have to be
pre-configured.
In addition to automatically launching `picocom` windows for each serial
port when the terminal server starts, ports that are added (hot-plugged)
while the server is running will have windows created for them
automatically, by way of a udev rule.
Each `picocom` process is configured to log communications with its
respective serial port. This may be useful, for example, to find
diagnostic messages that may not be captured by the `tmux` scrollback
buffer.
