How to Use minicom Super Terminal in Linux

System Environment: Ubuntu 9.10

1. Download and install minicom
Sudo apt-Get install minicom

2. Run minicom
Run the "sudo minicom-s" command to enter the configuration interface (or directly run "sudo minicom", Press "Enter + A", Press Z, and then press O, enter the configuration page)

+ ---- [Configuration] -------- +
| File name and Path
| File Transfer Protocol
| Serial port settings
| Modem and dialing
| Screen and keyboard
| Set to DFL
| Save the settings ..
| Exit
| Exit minicom
+ -------------------- +
3. Configure the serial port
Select "Serial Port Settings" to go to the serial port configuration page.
+ ----------------------------------------------------------------------- +
A-serial port device:/dev/ttys1
B-lock file location:/var/lock
C-Transfer Program:
D-call out program:
E-bps/PAR/bits: 115200 8n1
F-hardware Data Flow Control: No
G-Software Data Flow Control: No
Which settings do you Want to modify?
+ ----------------------------------------------------------------------- +

Select a serial port device: in Linux, The com0 port is/dev/ttys0, The COM1 port is/dev/ttys1, and my serial port is connected to the COM1 port. Therefore, select/dev/ttys1.
Set the baud rate and frame format to 115200 8n1 (115200 8n1: 115200 indicates the baud rate, 8 indicates the frame data length is 8, N indicates no parity bit, and 1 indicates 1 stop bit)

Because the serial port on my Development Board does not use hardware traffic control, set the hardware traffic control to "no ".
After setting, press enter to return to the main configuration page.

4. Save the Configuration
There are two Save options: "Save settings as DFL" and "Save settings .."
Set to DFL: Save the configuration as the default configuration. This configuration is automatically enabled when you run the "sodu minicom" command next time.
Set to ..: Save the configuration file. Enable the configuration file when "sudo minicom configuration name" is run next time. For example, if I save the configuration file as myconf, running "sudo minicom myconf" will enable the configuration.

5. Exit
Two exit options are available: exit and exit minico.
Exit: exit the configuration page and enable the current configuration.
Exit minico: Exit Software

6. Set to exit minicom at startup
After the device is started, press the "Enter key + A" button and Press X to exit minicom.

7. Enable the configuration file
Run "sudo minicom configuration name" to enable the configuration. If the configuration name is null, the default configuration is enabled.

Enter minicon next time.
The command minicom is used to enter the serial super terminal screen, while minicom-S is used to configure minicom.
Description:/dev/ttys0 corresponds to the port where serial port 0 connects you to the Development Board.

Note: If you disable minicom abnormally, several files (LCK *) will be created under/var/lock. These files prevent the running of minicom and can be restored after they are deleted.
