APCI3XXX_CONFIGURATION instruction requires 4 data parameters but
the comedi core sanity checks the INSN_CONFIG_DIO_INPUT instruction
which only has 1 data parameter. Because of this the (*insn_config)
function can never be called.

The (*insn_read) function is supposed to do "one-shot" or "software-
triggered" reads and return the data. The function in hwdrv_apci3xxx.c
does do this but it also is used to optionally start a "hardware-
