<p>Opens an FTP connection to the specified node.</p>
<p>You can open a connection for a particular <c>Name</c> and use the
same name as reference for all following subsequent operations.
If you want
the connection to be associated with <c>Handle</c> instead (if you,
for example, need to open multiple connections to a host), use
<c>Key</c>, the configuration variable name, to specify the target.
A connection without an associated target name can only be closed
with the handle value.</p>
