sible, but the receiver will buffer the data until enough bytes have arrived to cover worst case gaps
in transmission. The delay introduced by data buffering may range from 22 to 44 ms, but the radio
will not create any gaps in the output data stream. This mode of operation is required for protocols
such as MODBUS™ that do not allow gaps in their data transmission. [

NOTE:
With MODBUS/RTU mode, poll requests may be fragmented when using COM port baud rates
above 19200 bps via a USB/Serial adapter (FTDI). This may cause incorrect checksum/CRC
errors and thus, timeouts.
