; This sample shows how to access
; virtual ports (00000Fh to 0FFFFh).
; These ports are emulated in
; "EmuPort.io" file (saved in
; Windows "Temp" folder).
;
; This new technology allows
; to make external add-on devices
; for Emu8086, such as led displays,
; thermostat, stepper-motor, etc...
; "DEVICES" folder contains sample
; device that works with this sample.
; (with Visual Basic source code).
; Start "LED_Display.exe" before
; running this sample (from "Virtual
; Devices" menu of the emulator).
