Details
When a reset occurs, the digital line state can be read as high because the digital line is reset to a digital input
(see the mode command). A digital input floats high if nothing is connected to the digital line.
Set the state to zero (0) to clear the bit; any non-zero value sets the bit.
Example
:DIG:LINE1:STAT 1
Sets line 1 (bit B1) of the digital I/O port high.
