XBee Series 2 OEM RF Modules ‐ ZigBee ‐ v1.x2x [2007.07.019] Chapter 2 ‐ RF Module Operation
RTS Flow Control
If flow RTS control is enabled (D6 command), data in the serial transmit buffer will not be sent out
the DOUT pin as long as RTS is de-asserted (set high). The host device should not de-assert RTS
for long periods of time to avoid filling the serial transmit buffer. If an RF data packet is received,
and the serial transmit buffer does not have enough space for all of the data bytes, the entire RF
data packet will be discarded.
