USB-1208FS: Configure digital port. This command sets the direction of
the DIO port to input or output.
“DeviceIndex” is a small integer, the array index specifying which HID
device in the array returned by PsychHID(‘Devices’) is interface 0
of the desired USB-1208FS box.
“port” 0 = port A, 1 = port B
“direction” 0 = output, 1 = input
USB-1608FS: has only one port, so second argument is meaningless. If three
arguments are passed and device is a 1608FS, second argument is ignored.
Function could be made more efficient if a separate one were written for
1608FS, but I’m guessing this function will never be used at a time when
maximal speed is an overarching requirement.

USB-1024LS: Has three ports: 1 = port A, 4 = port B, 10 = port C (the sum
of: 8 = portC low, 2 = portC high). The card is verified to work well with
using port A or B for output and port C as a whole for input.
