The solution is to use a new com driver that can share interrupts. One was written called com-multiport by Chris Demetriou (cgd@berkeley.edu). I could not get it to work myself, but it was probably due to my own cluelessness more than the driver. I forgot where I found it, but it was nowhere exotic. john galbraith galbrait@rintintin.colorado.edu
