在屏幕上开出三个窗口：起止坐标为（5，10）和（15，30），（5，50）和（15，70），（18，15）和（22，65）。要求可用左右方向键选择左窗口或右窗口为当前活动窗口。当一行字符显示满后（左右窗口一行显示20个字符，下窗口显示50个字符），窗口自动向上卷动一行，输入的字符仍显示与最低一行，窗口最高一行向上卷动后消失。用上下方向键可使活动窗口及下窗口内容同时上卷或下卷。输入‘ESC’后结束程序。(huangyujie)-screen out three windows : starting and ending coordinates (5,10) and (15, 30), (5,50) and (15.70) (18.15) and (22.65). Asked about the direction keys can be used to choose the left or right window to window to window current activities. When his characters show after the expiration of (his show window about 20 characters, the next window displays 50 characters), the window automatically scrolling upward here, the importation of characters showed that the minimum here, his highest window scrolling upward disappeared. Up and down direction keys enable activities under the window and window content, but on the next volume or volumes. Importation "ESC" end after the procedure. (Huangyujie)

数字频率调制又称频移键控（FSK），二进制频移键控记作2FSK。数字频移键控是用载波的频率来传送数字消息，即用所传送的数字消息控制载波的频率。2FSK信号便是符号“1”对应于载频，而符号“0”对应于载频（与不同的另一载频）的已调波形，而且与之间的改变是瞬间完成的。 -Digital frequency modulation called frequency shift keying (FSK), binary frequency shift keying recorded as 2FSK. Digital frequency-shift keying is the carrier frequency to transmit digital information, that is, the number of messages transmitted with the control of the carrier frequency. 2FSK signal is the symbol of "1" corresponds to the carrier frequency, while the symbol "0" corresponds to the carrier frequency (with a different carrier frequency to another) and modulated waveform, but also between the change was instantaneous.
