mca_read_pos - read POS register from card
unsigned char mca_read_pos (int slot, int reg);
slot slot number to read from
reg register to read from
Fetch a POS value directly from the hardware to obtain the current
value. This is much slower than mca_read_stored_pos and may not be
invoked from interrupt context. It handles the deep magic required for
onboard devices transparently.
