I just put Debian 2.2r1 on my fiddlin' box and cannot get photopc to work with it. I get EIO errors with any application that tries to read or write to /dev/ttyS? as any user. The serial ports were accessible under the RedHat install I replaced with this one, so I know it's not a problem with the BIOS or hardware. I did an lsmod and have the serial module running. Any ideas? Thanks, Jason Majors
