Is there any documentation online on how to enable full duplex audio with newpcm? (See Colin's question below.)

Do you know if there's any documentation for the changes in the audio API in FreeBSD 4.0 available online? Probably there's now an ioctl() which is needed to enable full duplex, like on other platforms.
