modem/fh/rlink
This commands allows the user to specify the rate at which data is
transmitted over the RF link.
modem/fh/type
This command specifies the mode in which the radio modem will be
functioning. The FH modem supports three modes:
OFF
means that
the modem is turned off,
Receiver
means that the modem is used for
picking up the radio signals transmitted by the reference station’s
Structure

, where N is a number
between 0 and 4. 0 stands for 9600 baud, 1 stands for
12000 baud, 2 stands for 17000 baud, 3 stands for
24000, 4 stands for 51000.

The selection of 9600 baud provides the
maximum reliability for data communication
but it is achieved at the cost of reducing data
throughput. If, for some reason, you need to
have the maximum throughput, use 51000
baud, but please remember, that this link rate
has the lowest reliability for data
communication
