i have a very similar problem: trying to use a serial console (rs232c- cable attached to serial port /dev/ttyS0) with 'cu'. this used to work in older ubuntu-releases. this doesn't work anymore, and it is apparently not related to permissions. on the exact same hardware, this does work with with 'cu' under openbsd and netbsd.
