*The values for current 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 current (10 A).
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
(0 = NO 1 = YES)
10 Soft Start mode
(0 = NO 1=YES)
11 Water cooling
(0 = NO 1=YES)
