Log Message:
Adding ibmcd(4), a device driver for the IBM 4810 BSP cash drawer port as
found e.g. in SurePOS 300 series point of sale terminals. The driver
provides a gpio(4) device with three pins: pin 0 to open drawer, pin 1
to read the status and pin 2 to read whether a cash drawer is connected or
not.

+.Sh NAME
+.Nm ibmcd
+.Nd support for the IBM 4810 BSP cash drawer port
+.Sh SYNOPSIS
+.Cd "ibmcd* at at pci ? dev ? function ?"
+.Cd "gpio* at ibmcd?"
+.Sh DESCRIPTION
+The
+.Nm
+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.
+.Pp
+.Nm
+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.
+.Pp
+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.
+.Pp
+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.
+.Sh SEE ALSO
+.Xr gpio 4 ,
+.Xr gpioctl 8 ,
+.Xr ptcd 4
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Nx 6.1 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+driver was written by
+.An Marc Balmer Aq m...@msys.ch .
