I have a problem with buffered output streams:
If I make one by opening /dev/ttyb, it never gets flushed.
The only way to do this is to close the stream... Then everything I wrote to it is sent.
I didn't find any word about flushing in the manuals (Lucid), and apropos doesn't give anything valuable with "flush" or "empty" or "buffer".
How do these streams work ? Has anyone an idea ?
Thanks,
Eric
