Any ideas on how to get handshake/feedback on data transferred with Xtreme24's? I transfer a RS-485 signal between 2 Xtreme24 modules, but the transfer isn't reliable enough in areas where there's much Wifi equipment nearby, so I sometimes loose important bits of data. This would not be a problem if one had a way of feedback of the status of the data to the the sender before sending more data, like RS-232 have embedded.
