SIR is effectively an 16550 UART from what I've seen so far. > Maybe I'm missing something? Well, except that it has no flow control, is only half-duplex, and you might want to attach an IrDa stack to the device. If all the IrDa stack work is being done in userland, then this probably makes sense. If not, then at the very least, sio(4) needs to behave differently in the case of a SIR port. -- To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. - Theodore Roosevelt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
