     8== Parameters ==
     9
     10 * dev - 0 = main board input, DIO option card number
     11 * input number - option card inputs limited to two counters, any of inputs 1 - 7, and input 8 may be used.
     12 * reg - register to set
     13 * value - value to set
     14 * wait - WAIT_ACK to wait for acknoledgement or NO_WAIT_ACK for no wait.
     15
     16== Return Value ==
     17
     18 * Returns the result - OK success

     20== Remarks ==
