This seems to have the desired behaviour, I also added an 888 specific 
check so as not to change the behaviour for the other phidgets...

-Tom


static unsigned char digitaloutputs = 0;

enum ELPError phidgetInterfaceKitWrite(struct phidget *phidgetDevice, int index,
{
        char buffer[4];

        if (phidgetDevice->type->deviceClass == LP_INTERFACE_KIT_888) {
           if (value) {
              digitaloutputs |= 1 << index;
           } else {
              digitaloutputs &= ~(1 << index);
           }
           buffer[0] = digitaloutputs;
        } else {
           buffer[0] = index+(value << 3);
        }
        buffer[1] = 0;
        buffer[2] = 0;
        buffer[3] = 0;
        return(phidgetWrite(phidgetDevice,buffer,4));
}
