<Remarks>
FUNC 28 Bits 7 to 4 and Bits 3 to 0:
The bit settings allow the user to program the modem transmission attenuation level.
The smaller the set value, the higher the transmission level becomes. If errors occur
frequently or training is not sent, the transmission level should be changed, as a rule.
