Configuration of minicom in Linux

Mini-com is equivalent to a Super Terminal in windows. If I can use mini-com like a Super Terminal, it does not save me a lot of effort. So I tried to find out how to use mini-Com, I have said this before during my training. I am not very careful about it. When I went out to work on CPLD/FPGA, I found that arm + Linux is the foothold for finding a job.

On the Linux terminal, enter the command # minicom, So that I encountered the first problem: minicom: Warning: configuration file not found, Using defaults device/dev/modem access failed: Obviously, if there is no modem file or directory, it indicates you want to set the minicom configuration file. You can search for it under the/dev directory to see what serial device files are available. The command is as follows:

[Root @ localhost Dev] # pwd
/Dev
[Root @ localhost Dev] # ls TTYs *
Ttys0 ttys1 ttys2 ttys3
[Root @ localhost Dev] # ls Modem
Ls: Modem: the file or directory does not exist.
[Root @ localhost Dev] #

In Linux, TTYs * identifies the serial port. The serial port number is the serial port number. Generally, a PC is a serial port, which is also known as the comport (that is, the Tianhe Computer City with a computer ), don't talk nonsense. Set up the minicom configuration file. Professional Engineers will use # Man minicom, like me... It must have been checked online.

Enter # minicom-s under the terminal to enter the setting minicom Configuration window. The content is as follows:

┌ ── ─ [Configuration] ── ─ ┐
│ Filenames and paths │
│ File transfer protocols │
│ Serial Port setup │
│ Modem and dialing │
│ Screen and keyboard │
│ Save setup as DFL │
│ Save setup as .. │
│ Exit │
│ Exit from minicom │
└ ── ─

Here we need to set two options: Serial Port setup and modem and dialing. The first is Serial Port setup. Press enter to enter Serial Port setup settings. The settings are as follows:

Serial device: Corresponding Device File/dev/ttys0

The baud rate is set to, with 8 data bits and 1 Stop bits.

There is no hardware stream. This is common sense. In fact, I don't know why to set it like this ..
┌ ── ─
│ A-serial device:/dev/ttys0 │
│ B-lockfile location:/var/lock │
│ C-callin program: │
│ D-callout program: │
│ E-bps/PAR/bits: 115200 8n1 │
│ F-hardware Flow Control: No │
│ G-software flow control: No │
│
│ Change which setting? │
└ ── ─
Here I want to talk about it. I am stupid. It takes a while to preview and get started to operate these things. After exiting, I have to return and check whether there are any omissions. In short, enter the number before the option, then set it. The other words seem like I just came out of kindergarten.

Exit Serial Port setup and enter modem and dialing. The settings are as follows:

Specifically, remove a-initing string ...... :, B-Reset string ...... : K-hang-up string ...... The three configuration items are not clear. Let's look back at the project. Sometimes, I have to be "not seeking for a thorough solution". I still want to put my questions elsewhere.

 

┌ ── ─ [Modem and dialing Parameter setup] ── ─
│
│ A-init string ......
│ B-Reset string ...... │
│ C-dialing prefix #1... atdt │
│ D-dialing suffix #1 ...... ^ m │
│ E-dialing prefix #2... atdp │
│ F-dialing suffix #2 ...... ^ m │
│ G-dialing prefix #3... atx1dt │
│ H-dialing suffix #3 ......; x4d ^ m │
│ I-connect string ...... connect │
│ J-no connect strings .. no carrier busy │
│ No dialtone voice │
│ K-hang-up string ...... │
│ L-dial cancel string .. ^ m │
│
│ M-dial time ...... 45 Q-auto BPS detect ...... No │
│ N-delay before redial. 2 R-modem has DCD line .. Yes │
│ O-Number of tries... 10 s-status line shows... DTE speed │
│ P-DTR drop time (0 = No). 1 T-multi-line UNTAG... no │
│
│ Change which setting? (Return or ESC to exit) │

Then, exit and select the Save As DF1 option to save the modified configuration information as the default configuration option, and then exit from minicom ....
