%description:
Test that parameters of a channel can be changed from an other module's
initialize function (meaning that handleParameterChange is correctly called
in this case and the cached parameter values are refreshed correctly
in the channel object)

{
    parameters:
        delay = 1s;
        datarate = 5000bps;
