It should work, provided you setup the right modes and the data rates are matched in a way that you don't end up dropping stuff. However, there are simple, cheap serial/parallel converter boxes. Don't you think it would be simpler than running Unix to be a serial/parallel converter ? Cheers, Dan Ts'o dantso@cris.com
