Sender: owner-hardware@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I wonder if it might be crucial to use a FIFO sio rather than a normal 16550 in a serial card when dealing with modems at higher speeds. Is this an issue for FreeBSD given that the sios are interrupt driven anyway? --Chris Christoph P. U. Kukulies kuku@gil.physik.rwth-aachen.de
