Does it hang forever, or does it hang fdor 2 seconds (the timeout you specified)? In general, splitting the calls is probably not a good idea, since it doubles your system call overhead for work you have to do anyway. You might want to try it against /dev/null; it may be that your device driver writes end up being synchronous for the driver you are doing, and they may need to be reworked. The closest drivers to your hardware aren't network cards, they are actually sound card drivers. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
