Problem all gone. Thanks. : :Josh Uh huh. I had this same exact problem years ago. *YEARS* ago, and proposed something similar but got shot down. There isn't much of a point of having a serial FIFO if you program it to interrupt you a few bytes before it would otherwise overflow. This time I'm going to commit the change. Nay sayers can fix the serial fast interrupt or fix the system to not disable interrupts for long periods of time, and change it back AFTER they've done that. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
