ptcd
driver controls the cash drawer port of the
Protech PS3100 point of sale terminal using the GPIO subsystem.
ptcd
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.
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.
ptcd
driver first appeared in
NetBSD 6.1.
