Magnetic Stripe Reader
A 3-track MSR head is available as an option. The ISO card format is
supported.
When card data is read, an interrupt is generated. A software device
driver for the MSR must be loaded to enable the application to process
the data.
Touch Screen Controller
The MicroTouch "Excalibur" chip is used to interface the touch panel.
This controller supports MicroTouch capacitive panels.
In order to save an RS-232 port, the touch data is delivered to the
system through the mouse interface. This requires a mouse-aware
touch device driver for the appropriate OS.
When the system is operating in the dimmed display mode, touch
activity can restore full brightness if instructed by software to do so.
When system is in low power mode, touch activity can generate the
mouse port interrupt (IRQ12).
