Returns the value of the register copy kept by the Toolkit
for the equipment control register on the BigmOuth board.
Since the control register is not readable, the software must keep
a copy of the writes to the board in order to change selected bits
without modifying other bits. Reading the register copy reveals
the current state of the hardware. Paired with the SET_EQUIP_REG
command, this function can be used to change the equipment
register on the BigmOuth board without getting out of sync with
the Toolkit driver. See the Hardware Reference Appendix for the
function of the control port bits. |
