Yes; it would allow remote control protocols, and some IrDa self-clocking protocols that aren't possible if you treat the thing as an internally clocked 16550 with no special capabilities. It's like a parallel port that supports mode 1, 2, and 3, instead of just mode 1. Not that there's a driver for it that should prevent the SIO patch going in so we can at least use printers and PPP over IR, if we want. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
