How far does that extend? I get sio overflows all the time on my laptop; it just has a hardwired SLIP connection. I've got it down to 19200 baud (cables worked just fine at 57,6, couldn't tell at 115,2) and it still gets overflows every few minutes when I'm doing anything that passed data across the serial line. I assumed it was just the processor power (486 SLC/25) being slightly less than up to the higher data rates. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* | FreeBSD; the way computers were meant to be | * "The only reason I'm burning my candle at both ends, is * | that I haven't figured out how to light the middle yet."| * fullermd@futuresouth.com :-} MAtthew Fuller * | http://keystone.westminster.edu/~fullermd | *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
