Eric,

Thanks, that does help.
Are you able to comment on whether I 'should' be doing this as regards the non-blocking and non-seekable nature of a serial port?

Thanks,

Rob

A file_descriptor only implements the Device concept, it not an std::iostream.
If you want an std::iostream, you wrap the Device in a boost::iostreams::stream which, as stated in its documentation: "performs i/o by delegating to a contained Device", and "derives from a specialization of std::basic_istream, std::basic_ostream or std::basic_iostream, depending on whether the underlying Device models Source, Sink or both."

HTH,
