大家都来学DOS

其实DOS是很重要的,因为他和硬件结合得很紧密啊!
In fact, DOS is very important because it is closely integrated with hardware!

实在太牛了,我开始玩电脑的时候只听说过DOS
It's really amazing. When I started playing with computers, I only heard of DOS.

顶,我一直在dos下开发,用allegro+djgpp,盼望交流.QQ:729504816
私 下 交 流 不 如 公 開 討 論 , 大 家 都 得 益

Up, I've been developing under DOS, using allegro + djgpp, looking forward to communication. QQ: 729504816

既然是在dos下干活,你的工具软件和软件开发能亮亮底吗?
Since it's working under DOS, can you show the bottom of your tools and software development?

至少在DOS下控制下硬件要比WINDOWS方便的多,而且如果是做嵌入式的实时性方面也要好于WINDOWS来控制.对系统的资源比WINDOWS也要小的多.我是搞纺织机械方 ...
UCDOS会导致实时控制出现没规律的不稳定现象。我看过不少用WINDOWS的数控机床和专机,也没见过它什么时候不行了,WINDOWS也可以用I/O而且可以访问高于1M以上的硬件配置映像空间。只不过从DOS彻底转为WINDOWS需要2年左右的阵痛期。其实windows的主要咚咚就是INT 1EH和DOS的主要冬冬是INT 21H差不多,真正称得上内核的就HAL.DLL和NTOSKRNL.EXE(这两个会因ACPI的不同而不同),问题在于DOS的新设备驱动太少(而且就算有驱动也不完善),DOS几乎要全靠自己来完成很多设备的驱动,比如打印机,特别是USB打印机。
至于控制硬件,你不要操作系统,直接把程序写到MBR里面不是更方便,连重入问题都少很多,数据直接用INT 13H写入硬盘扇区、显示直接写屏,我们用操作系统主要是要用它的功能调用,请问DOS给你提供了哪些比较有用的功能调用?<img src="images/smilies/face-grin.png" align="absmiddle" border="0">

At least under DOS, controlling hardware is much more convenient than under WINDOWS. Also, in terms of real-time performance for embedded systems, it is also better than controlling with WINDOWS. The system resource usage is also much smaller than WINDOWS. I am in the textile machinery field...
UCDOS can cause irregular and unstable phenomena in real-time control. I have seen many CNC machine tools and special machines using WINDOWS, and I have never seen when it didn't work. WINDOWS can also use I/O and can access hardware configuration memory spaces above 1M. It's just that the painful period of completely switching from DOS to WINDOWS takes about 2 years. Actually, the main things of windows are INT 1EH and the main things of DOS are INT 21H, roughly the same. The real kernel-like ones are HAL.DLL and NTOSKRNL.EXE (these vary depending on ACPI). The problem is that there are very few new device drivers for DOS (and even if there are drivers, they are not perfect). DOS almost has to complete the drivers for many devices all by itself, such as printers, especially USB printers.
As for controlling hardware, if you don't use an operating system, directly writing the program to the MBR is more convenient, and there are fewer reentrancy problems. Data is directly written to the hard disk sectors using INT 13H, and display is directly written to the screen. We use the operating system mainly to use its function calls. So, what useful function calls does DOS provide? :lol:

感谢大家看得起我

好久好久不来,不想我的帖子引起这么多跟帖。
为表示对大家的感谢,正好近来在整理以前的一些东西,遂把新开的网志里的文章全部贴了出来,希望能对大家有所帮助。
近期及今后还会陆续出一些文章,请关注我的网志:
http://hengch.blog.163.com
正在整理的文章有一篇关于CWSDPMI下硬件中断较深入一些的文章和一篇关于BT878编程的文章,敬请关注
Long time no see. I didn't expect my post to get so many replies.
To express my gratitude to everyone, and since I've been sorting out some old stuff recently, I've posted all the articles from my newly opened blog. I hope they can be helpful to everyone.
There will be more articles in the near future and beyond. Please follow my blog:
http://hengch.blog.163.com
There is an article about in-depth hardware interrupts under CWSDPMI and an article about BT878 programming being sorted out. Stay tuned

好!
如果中国能有多几位象“楼主”这样精通软硬件的人才就好了!
Well!
If China could have more talents like the "thread starter" who are proficient in both software and hardware, that would be great!

用个200的CPU,做图像采集实时性巨好。还有什么可说的。
Using a 200 CPU, the real-time performance of image acquisition is extremely good. What else is there to say?

搞嵌入式的,能用单片机完成的,尽量不用PC完成,能用dos完成的,尽量不用linux完成。windows?算了吧...
For those doing embedded systems, if a task can be done with a microcontroller, try not to use a PC for it. If it can be done with DOS, try not to use Linux for it. Windows? Forget it...

系统也好,编程语言也好,鄙人认为没有好坏之分,关键是他们能做什么,而你要用他们做什么!!用最简洁的方法达到最满意的效果,是每一个程序员所追求的!!其他的,我只能说是个人所好而已!!当然,从在商业上考虑,最低的成本,最好的通用性,维护性也不可忽略!!
Systems, programming languages, etc., I don't think there is a distinction between good and bad. The key is what they can do and what you want to do with them!! Using the most concise method to achieve the most satisfactory effect is what every programmer pursues!! As for others, I can only say it's a matter of personal preference!! Of course, from a commercial perspective, the lowest cost, the best versatility, and maintainability cannot be ignored either!!

电信级的设备用win平台估计是没事找抽型的。
Using a Windows platform for telecom-grade equipment is probably a case of asking for trouble.
