Little problem which may be related to my Potato setup. My two serial ports don't work - setserial always returns "Input/output error," even when I try just the -g parm, or with autoconfig. stty returns the same thing. The hardware is fine, since it works with SuSE 6.4 and various versions of lesser OSs. CMOS setup verifies that serial ports are setup correctly, using conventional default settings.
/var/log/dmesg shows... Serial driver version 4.27 with no serial options enabled ttyS00 at 0x03f8 (irq = 4) is a 16550A ttyS01 at 0x02f8 (irq = 3) is a 16550A Serial ports are, I believe, "16550A equivalent," (ASUS P3B-F motherboard) and the settings shown in dmesg are correct. Serial driver is loaded, and (default Debian install) kernel looks like it supports serial. (I tried removing CONFIG_SERIAL_NONSTANDARD=y, for yucks, but no difference.) I get exactly the same result when I disable the onboard serial ports and try a four-port FlexPort, though the FlexPort also works under other OSs. Also the same when I boot harddisk from a different (identical) machine. I'm SURE that this is something real simple, but I've read the Serial HOWTO from cover to cover, but got no clues. Disregarding the serial problem, BTW, I couldn't be happier with 2.2. Can anyone help me figure this out? Thanks... -jeff
