*The values for power and voltage are given as numbers,
scaled from 0 to 255, where 0 corresponds to 0 V and 255
to the full scale voltage (100 V) or power (500 W).
When the Request is "G", the Answer will contain a string
of 12 characters with the following parameters:
Bytes
1
Speed adjust value (in KRPM)
2-3
Pump cycles number (integer coded in 2 bytes)
4
Speed threshold
5-8
Run up time in seconds
(long coded in 4 bytes)
9
Deat time

When the configuration parameters have to be changed,
send a Request string with "H" characters of the following
type:
"H" + .... DATA .... + CRC
The CRC is calculated on the string consisting of
H + DATA.
The following parameters can be changed:
Bytes
1
Speed adjust value (in KRPM)
2
Speed threshold
3-6
