If you have the SIO driver in the kernel at all, it will probe for all four com ports. Com3 is at 2e8. To build a kernel with SIO, you will need to remove Com3 from the list of probed SIO devices. You can do this by modifying the sio driver source. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
