I am using a laptop, so I encountered a problem of USB to serial port. First, check whether there is a USB-to-serial driver in ubuntu)

I found that there is no ttyUSB0 file in/dev, but www.linuxidc.com can create one by itself:

Sudo mknod/dev/ttyUSB0 c 188 0

If you are using a serial line, set it to/dev/ttyS0.

Then we re-enter minicom For Configuration:

Sudo minicom-s

Select Serial port setup and perform the following settings:

| A-Serial Device:/dev/ttyUSB0 |

| 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 |

After setting, select Save setup as dfl so that you do not need to reconfigure it next time.

Connect the USB to the serial port and restart minicom.
