GET CURRENT MOVE
Get the digital potentiometer whiper setting, controlling the stepper driver current.
(uint8 [0-127])
Example command:
$BS GET CURRENT_MOVE\

CURRENT HOLD
The motor current while in holding position (not moving). The CURRENT HOLD value is the digital
potentiometer whiper setting controlling the reference voltage, which is inversly proportional to the
stepper driver current in STOPPED state.

(uint8 [0-127], DEFAULT = 100, Safetly limit=10).
SET CURRENT HOLD
Set the CURRENT HOLD variable. Example command:
$BS SET CURRENT_HOLD:100\

GET CURRENT HOLD
Get the digital potentiometer whiper setting, controlling the stepper driver current while the focuser
is STOPPED (uint8 [0-127], DEFAULT = 100).
Example command:
$BS GET CURRENT_HOLD\

Example answer:
$BS STATUS CURRENT_HOLD:100\

RCX
Set the RCA and RCB digital potentiometer whiper setting, controlling the Bridge A/B blanking
and off time of DRV8811 stepper driver (uint8 [0-127]). But beware, setting a too short off-time will
overheat the stepper motor! This is an expert setting and should only be changed if using a different
stepper motor.
SET RCX
Set RCX variable. Example command:
$BS SET RCX:64\
