You've missed the point. The sio overflow problem isn't caused by data coming in too fast. The sio buffer just isn't flushing, it seems. I did try a slower speed initially but it doesn't matter what speed it runs at; if the buffer isn't flushed, the next nugget of data that comes in from the port overwrites what's sitting in the buffer and thus the sio overflow. For reference, this serial port is connected to an ISDN TA and is often doing a 2B (128k) connection to my ISP. ---------------------------------------------------------------- Dave Cole (DC1110) | dacole@netcom.ca Systems Administrator |* dacole@rik.net * | office/~dacole/ Netcom Canada |* www.rik.net/~dacole/ * 905 King Street West, Toronto, M6K 3G9 | phone - 416.341.5801 Toronto, Ontario, Canada, Earth, Sol | fax - 416.341.5725 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
