Cool! I've got a Psion S3a on a ttySx port attached.

Sorry, I've tested it with with my Psion S3a and an old 9600 bps modem.
Even if the modem has no connection, it does not work. I think, that the
kernel does not know, which port has data when the shared interupt occurs.
So I have taken every port to it's own interupt. But my question is: Why
can I share interupt with parallel ports? I have lp1 and lp3 on the same
interupt, and printing and the access to my Zip drive works fine!
