a <n>
Absolute Position (Not Busy)
This is the same as the [A] command, except that the status bit within the
reply string indicates that the pump is not busy.
P <n>
Relative Pickup
The [P] command moves the plunger down the number of increments
commanded. The new absolute position is the previous position plus <n>,
where
<n> = 0..6000 in standard mode and
<n> = 0..48000 in fine positioning and microstep mode.
For example:
The syringe plunger is at position 0. [P300] moves the plunger down 300
increments. [P600] moves the plunger down an additional 600 increments to
an absolute position of 900.
The [P] command will return error 3 (invalid operand) if the final plunger
position is greater than 6000.
p <n>

string indicates that the pump is not busy..
D <n>
Relative Dispense
The [D] command moves the plunger upward the number of increments
commanded. The new absolute position is the previous position minus <n>,
where
<n> = 0..6000 in standard mode and
<n> = 0..48000 in fine positioning and microstep mode.
