Subject: serial device and fsync
Date: Mon, 25 May 2009 12:50:22 +0300	[thread overview]
Message-ID: <dfb262380905250250w2d689b28i25edc3d492b09676@mail.gmail.com> (raw)

Hi all,

I need to write(2) a certain character to a serial device (using the
standard /dev/ttySx), and make sure it was transferred to the device
before I continue. I tried fsync(2), but that failed (does fsync even
apply to character devices or only block devices ?).

Any idea ?

Is it even possible or should I just usleep(500ms) after write(2) ? (I
know, it's ugly..).

Thanks in advance,
Naziir.
