Some buggy UARTs drop control lines when the baud rate is set, even if it's being set to the current value. There used (eons ago) to be a patch for this (don't set the baud rate if it's already the desired value); someone who knows the driver better than I do should check that it's not still a problem. -- Bob Bishop +44 118 977 4017 r...@gid.co.uk fax +44 118 989 4254 (0800-1800 UK) To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
