    Yet another USSD topic - app hungs on reading from RComm

    I've read these two topics on mixing qt and symbian code and using RComm
    http://www.developer.nokia.com/Commu...2B%2B_Together
    http://www.developer.nokia.com/Commu..._USSD_commands

    and came with following test app:
    * simple gui to enter ussd string
    * CActive based async private implementation behind qt api
    * even add sync routine
    Compileable code attached.
    I test it on my N8 and got following: both sync and async routine never
    completes request RComm::ReadOneOrMore (sync version hungs and
    async never enters CActive::RunL second time).

    Here's link to source in my dropbox folder http://dl.dropbox.com/u/28264752/ussd.zip

    Haven't checked your code thoroughly - just a quick check: the Symbian code you're using requires an extensive capability set, are you using a proper developer certificate? If not, then the target binaries are automatically 'patched' by the build tools to remove any capabilities that the certificate does not allow.

    Sure. Last time I try QtSDK refuses to create sis file when capability in pro file not
    present in cert.
