Configuration
This message downloads and activates (so becoming the current
configuration) a configuration to the Modulator. The configuration structure
can be upgraded by defining a new protocol version number and adding
the extra fields required at the end of the message.

Bit-rate
Set interface bit-rate, 1 bit/s increments. This value
is only used if Symbol rate is set to 0xFFFFFFFF.
Byte 1: Bit-rate bits (31..24)
Byte 2: Bit-rate bits (23..16)
Byte 3: Bit-rate bits (15..8)
Byte 4: Bit-rate bits (7..0)
e.g. 155 Mbit/s = 0x093D1CC0
4
Symbol
rate
Set symbol rate, 1 symbol/s increments. This value
is used by default unless set to 0xFFFFFFFF in
which case bit-rate will be used.
Byte 1: Symbol rate bits (31..24)
Byte 2: Symbol rate bits (23..16)
Byte 3: Symbol rate bits (15..8)
Byte 4: Symbol rate bits (7..0)
e.g. 30 Msymbol/s = 0x01C9C380
