Does anyone have the RS-232 commands in ASCII or Hex format for selecting ports 1-8 on the Xantech RS2321X8? I'm using this router in conjunction with my Pronto TSU9600 remote and RFX9600 Serial Extender. Have no issues selecting ports 1-8 using IR. Would rather not waste an IR port on my serial extender if I don't have to however, as I could just as easily select a given port using RS-232 if I only had the needed commands.
