I'm not sure... you want to print the hex values of chars, but *not* on the same output as your regular stdout? Try this: - Make a new block that converts chars to ASCII-hex (e.g. w/ sprintf) - Connect that block to a gr_file_sink (or a gr_file_descriptor_sink), and write to a file (or a named pipe). - When the flowgraph is running, open a separate xterm, and in there, do a 'tail -f FILENAME' (or 'cat PIPENAME'). The file approach will create a massive big text file, but perhaps you want that. MB -- Karlsruhe Institute of Technology (KIT) Communications Engineering Lab (CEL) Dipl.-Ing.
