Uartstream.send returns SUCCESS or FAIL depending on whether the request was accepted or not. Uartstream.sendDone signals whether the bytes were successfully sent or not. You should check these returned values before issuing Uartstream.receive. If you have written your own modules/code for RS485 that provides Uartstream interface then you should make sure that these returned values are appropriate.
