NAME

     ibmcd -- support for the IBM 4810 BSP cash drawer port


SYNOPSIS

     ibmcd* at at pci ? dev ? function ?
     gpio* at ibmcd?


DESCRIPTION

     The ibmcd driver controls the cash drawer port of the IBM 4810 BSP PCI
     device found in IBM point of sale terminals (e.g. in the SurePOS 300
     series) using the GPIO subsystem.

     ibmcd provides a GPIO device with three pins: pin 0 is used to control
     the cash drawer while pin 1 can be used to read the current state of the
     sense input pin.  A logical 0 means the cash drawer is closed, a logical
     1 means the cash drawer is open.

     Pin 2 reports if a cash drawer is connected.  A logical 0 means there is
     no cash drawer connected, a logical 1 means the cash drawer is connected.

     To open the cash drawer, set pin 0 to logical 1.  There is no need to
     reset pin 0 to logical 0 afterwards as the device generates a oneshot
     impulse.
