Chapter 173 Chinese Character Environment and Cat (3k)
In the morning, Gao Zhendong came to the computing office with a tape.
Ever since he saw Mr. He and the others working hard to copy his manuscript at the Prairie Tractor Factory, he realized a problem. There was a work schedule that should be advanced, and there was something wrong with the previous plan.
That is, the priority of the Chinese character editing environment, Chinese character operating system, or even just the operating system is not as good as this.
With this thing, computer promotion has another pillar: office.
Although it is difficult to find a unit that is willing to use DJS-59 for office work now, this is a trend. One of the biggest advantages of electronic data-the ease of copying has not yet been fully demonstrated.
For today's people, even if it is a text editing software without any formatting, as long as the first line can be indented by two spaces, it is basically usable.
Fortunately, he has already implemented all the vi-like editor and display drivers. Based on these two things, he can edit and display Chinese characters very quickly.
It took him a day to complete the editing and display functions of Chinese characters. The only problem was the font library and input method.
He made a 16*16 dot matrix font for four Chinese characters: one, two, three, and already.
The input method he chose was Quanpin, which is the simplest Chinese character input method and requires no brain work. However, he only made four corresponding input codes and words, one, two, and three.
Needless to say, one, two, and three, these are the simplest Chinese characters. It saves trouble and is enough for debugging. And the "has" is prepared for the homophone selection function of the input method.
Thousands of 16*16 dot matrix fonts for commonly used Chinese characters, as well as the correspondence between input codes and characters, plus all the 16*8 fonts of English and punctuation that need to be redone to ensure display consistency. Dot matrix font library, this workload is not small.
This is a strenuous job, so he made a decisive decision to shake people! Shake people from calculations.
Bringing the tape, I found Chief Engineer Chi of the Computing Office. Chief Engineer Chi was very happy when he saw Gao Zhendong coming with the tape again. It seemed that there was something new.
Several key members were gathered and surrounded Gao Zhendong.
With the rustling sound of the tape, Gao Zhendong opened the vi editor. The people in the computing office looked at him, a little confused. What's new about this thing?
But as Gao Zhendong entered "yi" on the keyboard, a line of alternative words "1.一2.有" popped up at the bottom of the screen, and everyone's eyes widened.
Gao Zhendong pressed the "1" key on the keyboard, and the word "一" flashed on the screen.
Everyone was excited and wanted this thing for a long time.
Chief Engineer Chi stood behind Gao Zhendong and patted him hard on the shoulder: "Director Gao, you have created a Chinese character editing environment!! Great, from now on, our text will also be in the computer!"
“You can use computers to write documents in the future. You don’t have to worry about typos or wasting pen and ink.”
“Don’t you think using computers to write documents is a greater waste?”
“Great, from now on, comments in C language programs can be written in Chinese characters, instead of writing a bunch of pinyin that you have to guess by connecting them together like before.”
< br>“Don’t mention it, using tapes to store files is so exciting just thinking about it.”
"If you think about it carefully, it is really convenient to modify files on the computer."
Due to the existence of polyphonic characters, writing comments in Chinese Pinyin requires you to guess after a long time, so many There are actually quite a lot of problems with the country’s pinyin script.
For example, in a certain country, because "waterproof bolts" and "water drain bolts" have the same pinyin, the wrong bolts were used and the foundation was soaked.
Gao Zhendong then entered the words "two", "three" and "has", and then said with a smile: "No more."
Chief Engineer Chi: "No more ?”
Gao Zhendong smiled and said: "Yes, I spent a day writing this thing. I was alone and didn't have time to make a font library and input correspondence table, so I just made these few words for debugging."
Everyone laughed, this is indeed not something one person can do in a short time.
Then he suddenly reacted: "One day? Director Gao, it only took you one day to make this thing?"
Gao Zhendong nodded: "Well, yes, there is a ready-made editor. The editor and monitor graphics driver are the foundation, and C language programming is more efficient than assembly, so this thing is quite simple.”
Although the editor is implemented in assembly, the advantage of C language is that it can be directly used. Programs embedded in assembly can also be compiled and run.
Chief Engineer Chi didn't know what to say. Although he knew what he said was right, he was still surprised that he could make this thing in one day.
Gao Zhendong said: "Next, the production of the Chinese character library and the preparation of the input correspondence table will be left to you. I really don't have time."
Chief Engineer Chi was excited Patting his chest: "Director Gao, don't worry, we will leave this matter to us! Unfortunately, computers are a bit expensive now. Those who can use this to edit files are really not ordinary people, haha."
Gao Zhendong laughed. Gao Zhendong smiled and said: "Maybe in a few years, it will be popularized soon." After instructing Chief Engineer Chi to make a Chinese character library and input correspondence table as soon as possible and return a copy to him, Gao Zhendong left the computing office.
Chief Engineer Chi immediately called the leader of the 12th Machinery Department.
"Leader, good news."
The leader of the 12th Machinery Department smiled: "What good news? So excited."
"The senior officer of the Third Steel Rolling Plant Director Zhendong has created a Chinese character editing environment. From now on, we can edit and process files on the computer."
The leader of the 12th Machinery Department answered the call and stood up from his chair.
"Good news, this is really good news."
"Yes, leader, editing and processing files on the computer is easy to save, flexible to modify, easy to copy, and it is also easier to encrypt than ordinary files. Between various units It will be more convenient to transmit data. "
What Chief Engineer Chi has not yet imagined is that when the "computer-to-computer communication" technology proposed by Gao Zhendong comes to fruition, it will bring about greater changes.
He then introduced the current status of the Chinese character editing environment to the leaders of the 12th Machinery Department. The leaders were very happy to hear this: "This matter is of great significance. Wait until you complete the Chinese character library and input method mentioned by Director Gao. Then tell me, I will contact the people at the publicity office and ask them to go to your place to take pictures. This matter needs to be publicized!"
Chief Engineer Chi agreed repeatedly, and the leader of the 12th Machinery Department said regretfully: "You said this! Director Gao, why are you assigned to the 17th Machinery Department? What a waste of talent!”
When Chief Engineer Chi heard this, he thought to himself, don't let the leader of the 17th Machinery Department hear what you said, otherwise he will definitely use Director Gao's other achievements to spray you.
Gao Zhendong didn't know this. He was in his office, looking at his new gains in the system store.
He came up with it on a whim after seeing a mobile wifi terminal.
Then he got the big tin box in front of him and an instruction manual.
This is a modem used on telephone lines. Gao Zhendong only heard of its name in his previous life, but had never seen it, because at that time, this thing had been eliminated for more than ten years, except for many In special places and situations, no one uses this thing at all.
Modem is the abbreviation of Modulator and Demodulator. The modulator is responsible for modulating the digital signal sent by the computer into an analog signal that can be transmitted by the telephone line, and the demodulator does the opposite.
When the two work together, remote communication can be achieved through telephone lines. In fact, this thing does not necessarily need to go through telephone lines. In theory, it only needs a pair of wires.
Due to the pronunciation of Modem, people in previous lives nicknamed this thing "cat". It was once a standard feature on computers, both external and built-in.
Gao Zhendong almost screamed with excitement.
At this time, there is a modem in Citi, but there is still no modem in China. Now, you can set up a simple network!
The speed of this thing is not high. In the previous life, the maximum speed was basically 56kbps, and the one Gao Zhendong has is 1200bps, which means 1200 bits can be transmitted in one second. It doesn’t seem high, but for computers of this era, Said, this speed is very sufficient.
Without saying anything, Gao Zhendong extracted another one, two more from the system! This time I can receive and send one at a time.
But he was not in a hurry to take it to the computing office. He still had to make some preparations.
What can we do if we only have the device but no driver and application software?
telnet, ftp!
With these two things, one can send messages and the other can send files.
Telnet and ftp are two application layer protocols based on the TCP/IP protocol. Telnet is also one of the basic protocols for computer remote login and has many uses.
Thinking of this, Gao Zhendong did not hesitate to use 4 lottery opportunities to find a set of books in the system.
——"Detailed Explanation of TCP/IP Protocol"!
Citigarians, your TCP/IP is now ours!
Of course, it is unrealistic to implement the huge TCP/IP protocol suite immediately. It just cuts out telnet and ftp from it. Even the protocol data packets are not necessarily carried on TCP or UDP packets.
The specific implementation of TCP/IP will be discussed later. I will build a network first.
Read the manual of the modem carefully. It is actually the design material. This thing may be complicated, but it is really not that complicated. It uses phase shift keying (PSK) technology for modulation and demodulation. PSK Simply put, it uses different phases of signals to represent binary "0" or "1".
Of course, modulation and demodulation are not limited to phase shift keying. There are also many types of modulation and demodulation, such as frequency shift keying (FSK), amplitude shift keying (ASK), and quadrature amplitude modulation (QAM), but they are not too high. The two machines Zhendong has are using PSK.
The components used are basically replaced with domestic components, which makes it easy for Gao Zhendong to explain the origin, but he still has to ask his father-in-law to buy several sets of components based on the BOM list of this thing. Come on, cover it up. As for the circuit board, let the people at the computing center do it and send it over to you.
