Hi, I have a PS+ and I've used several USB to RS232 adaptors with ZERO problems. The one I use most often is the IOGEAR GUC232A. Cost me $15 and it has worked fine with the PS and everything else I've used it on including MAX232 based interfaces to PIC projects. --Chris http://www.rocklizard.org Chris@rocklizard.org ------------------------------------ 12x2 LCD displays & serial LCD interface chips available.
