[SOURce:]DIGital:DATA
This command sets and reads the dc source digital control port when that port is configured for Digital I/O
operation. The port has three signal pins and a digital ground pin. Pins 1 and 2 are output pins controlled
by bits 0 and 1. Pin 3 is controlled by bit 2, and can be programmed to serve either as an input or an
output. It normally serves as an output. Bit 2 must be programmed high to use pin 3 as an input. Pin 4 is
the digital ground. The query returns the last programmed value in bits 0 and 1 and the value read at pin 3
in bit 2.
