<title>Vanilla Driver</title>
<p>
The old previously documented support for opening a port to an
external resource by passing an atom (or a string) as first
argument to
<seemfa marker="erts:erlang#open_port/2"><c>open_port()</c></seemfa>,
implemented by the vanilla driver, will be removed in OTP 27.
This functionality was marked as obsolete about two decades ago
and then a few years later the documentation for it was removed.
If this functionality is not used with care it might hang or crash
the runtime system.
