The Baud Band command sets the Baud Band for the over-the-air data.
The range of this value is 1 to 4 as shown in Figure 7. This command is the
equivalent of the BAUD0 and BAUD1 lines.

Figure 7: NT Series Transceiver Baud Selection
The transceiver has an optional internal packet generator that can be used
instead of a custom protocol. Please see the Packet Generator Reference
Guide for more information on Packet Mode. In Packet Mode, this value sets
the over-the-air baud rate as shown in Figure 8. This does not affect the baud
rate of the Command Data Interface. Using a lower baud rate results in better
range.

Figure 8: NT Series Transceiver Packet Mode Baud Selection
The TX / RX Mode command puts the transceiver into Receive Mode or
Transmit Mode. This value is 0 for receive or 1 for transmit. This command is
the equivalent of the T/R_SEL line. Note that this command is ignored when the
transceiver is in Packet Mode.
