       Users that have previously registered SIO can use REREG.EXE to
       transfer the registration information to a new version of SIO. 
       Simply unzip the new SIO files into a temporary directory, change
       to that directory, execute REREG and answer the questions.

       If REREG will not transfer your registration information from a
       previous version of SIO to the new version, then an upgrade must
       be ordered on disk.

       If:
            1 - You have an Internet address or CompuServe address
            2 - You can accept uuencoded files (if Internet)
            3 - You registered SIO for more than 4 ports

       then upgrades will be Emailed to you (upon request) at no charge. 
       It is too expensive to send files via FidoNet.
