is_connected: BOOLEAN
writable attribute
{ANY}
top
True if the stream is connected.
Only in that case can data be transferred via this stream.
can_put_character (c: CHARACTER): BOOLEAN
effective function
{ANY}
top
disconnect
effective procedure
{ANY}
top
Try to disconnect the stream.
Note that it *does not* ensure that the stream will effectively be disconnected (some terminal streams, for instance, are always connected) but the feature can be used to "shake off" filters.
