+ <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.
+ </p>
