[PHREAKSCRIPT-62] res_smdr_whozz: Initialization usually fails in practice
In practice, res_smdr_whozz usually fails to initialize successfully.
The workaround has been to connect to the serial port using screen and send @ (which will cause a # echo). I don't know if interaction is actually required though, that needs to be tested further.
Afterwords, refreshing the module will result in successful initialization.
Clearly, screen is doing something that seemingly "makes the serial port work", and the module should do that so this voodoo dance isn't needed.
