description:
ptcd(4) is a device driver for the cash drawer port found on Protech PS3100
point of sale terminals. It controls the cash drawer using a gpio(4) device
that attaches at ptcd0: Pin 0 controls the drawer, pin 1 reports the current
state. For details read the manual page.

+.Sh NAME
+.Nm ptcd
+.Nd support for the Protech PS3100 cash drawer port
+.Sh SYNOPSIS
+.Cd "ptcd* at isa? port 0x48d"
+.Cd "gpio* at ptcd?"
+.Sh DESCRIPTION
+The
+.Nm
+driver controls the cash drawer port of the Protech PS3100 point of sale
+terminal using the GPIO subsystem.
+.Pp
+.Nm
+provides a GPIO device with two 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
+To open the cash drawer, set pin 0 to logical 1 for a short period
+of time (e.g. < 1 sec) and then reset the pin to logical 0.
+.Sh CAVEATS
+As it is not possible to detect the hardware at runtime, this driver, when
+enabled, will always attach.
+Only enable it in your kernel configuration if you have the proper hardware.
+.Sh SEE ALSO
+.Xr gpio 4 ,
+.Xr gpioctl 8
+.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 marc%msys.ch@localhost .
