ibmcd -- support for the IBM 4810 BSP cash drawer port
ibmcd* at at pci ? dev ? function ?
gpio* at ibmcd?
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
gpio(4), ptcd(4), gpioctl(8)
The ibmcd driver first appeared in NetBSD 6.1.
The ibmcd driver was written by Marc Balmer <email@example.com>.
