#Minicom serial port software

The serial port setup->Hardware Flow Contorl option was changed to Yes. I found that the key point is in the configuration of the serial port.

When using minicom to view the log, today I found that I could not enter the command line mode to enter the command. After all configurations are completed, press Enter to return to the previous interface, select save setup as dfl (that is, save the default configuration), and then select Exit to close minicom.Д®nter the command sudo minicom again, the configuration just now takes effect, you can see the serial port output information

Then continue to configure the software flow control, and select NO. Use the arrow keys to select Serial port setup, press Enter to enter the setting environment, as shown in the figure belowДЄfter configuring the serial device, press Enter, then enter E, configure the baud rate, and press the default configuration to be 115200 8N1 (Baud rate: 115200, data bits: 8, parity bit: N none, stop bit: 1 ).ДЄfter configuring the baud rate, press Enter, then enter F, configure hardware flow control, and select NO Press ctrl-a x or ctrl-a q to exit minicomД®nter sudo minicom -s, and note that sudo must be added in the front, otherwise the permission issue of 'cannot write to /etc/minicom/minirc.dfl' will appear after we configure!
