I am using the DE620 and Bjorn Ekwall's driver with a Thinkpad
340 and kernel 1.3.9. I would like to use the DE621 addon
multiplexer (into which are plugged the printer and DE620).
However, Ekwall's driver seems not to support this. Is there
another driver around? What needs to be sent to the DE621 to
make it switch from the printer to the ethernet adaptor?
