介绍用Java解析网络数据的三种特殊方法

; This short program for Emu8086 shows
; how to keep constant temperature using
; heater and thermometer (between 60 癈 to 80 癈),
; it is assumed that air temperature is lower 60 癈.

; "Thermometer.exe" should be copied to "DEVICES" folder
; of Emu8086 (to enable running it from the menu).

; WARNING! DO NOT RUN TWO OR MORE INSTANCES OF 
; "Thermometer.exe", THIS WILL CAUSE A DEVICE CONFLICT
; AND HEATER WON'T OPERATE CORRECTLY.

; Temperature rises fast, thus Emulator should be set
; to run at the maximum speed (set "step delay" to zero).

; The code is fully demonstrational, 癈 can be replaced
; by 癋 without any doubt.

; For questions please feel free to e-mail:
;     [e-mail]

; You should have Emu8086 to run this code,
; the latest version of Emu8086 can be found here:
