Minicom can't input the problem solution

When using minicom to view the log, I found that I can't enter the command line mode input command today. I found a key port setup in the serial port configuration by finding the data. The >Hardware Flow Contorl option was changed to Yes, which caused the keyboard to be useless and could not accept any input. Just change him to No. The specific modification is as follows:

sudo minicom -s

+-----[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 | +--------------------------+

Enter the Serial port setup interface

+---- -------------------------------------------------- -----------------+|  A - Serial Device : /dev/ttyS1 | |  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? | +------------------------------------------------- ----------------------+

At this time, the F-Hardware Flow Contorl item is Yes. Press F to change it to No. That is to close the hardware flow control, press Enter to return to the previous menu

+-----[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 | +--------------------------+

Select|  Save setup as dfl | Then select Exit from Minicom and restart minicom

so you can enter the command.
