We are working on pxa27xboard based on WIN CE 5.0. Currently for OS the TCP/IPv4 seems to be under default. I would like to set TCP/IPv6 by default , but I don’t know what to do and upload the writing. At the category TCP/IPv6 has been added. Looking at the reginit.ini file the TCP/IPv6 related registry is not included. In addition looking at the public the TCP/IPv6 related registry is not included. If you let us know how to set it would be appreciated.
