Remarks on program function
The data for keyboard of type Generic COM device can be updated, i.e. created, changed or deleted, with this program. Data which has already been stored can be displayed.
This device is similar to the Generic PS2 device. It allows for connection of read-only devices, e.g. magnetic card readers, waiter lock, scanner or central lock. This device also supports the operation of two devices on one COM interface, e.g. Generic display.
Note:
The MICROS Retail OSCAR POS application allows the configuration of 3 different generic entry
devices; two for connection to the PS2 interface and one for connection to the
COM interface.
· PS2 keyboard ( -> PS2 interface)
· Generic PS2 device ( -> PS2 interface)
· Generic COM device ( -> COM interface)
General information and examples of configurations for these devices can be found under Documentation configuration generic keyboards and input devices.
