Re: [Discuss-gnuradio] fifo / file source

[CEL]

Hi Ali,

it's not quite certain which program you run in that terminal, but:
File I/O is usually buffered, and this sounds like the data is never
written to your FIFO before you exit your terminal program.

Solution: Use a terminal program that doesn't buffer or flushes
regularly.

Best regards,
Marcus
