It can work just fine using serial communications over a single pin.......provided you use the software serial commmands (i.e. SERIN/SERIN2/SEROUT/SEROUT2/DEBUGIN/DEBUG, etc.) and not the hardware or it's commands (i.e. HSERIN/HSERIN2/HSEROUT/HSEROUT2). PBP should/will automatically set the pin to input and/or output as required...should that is.
