Solutions to “Can Not Type in Minicom”

Now that we’ve identified the possible causes, let’s move on to the solutions. Follow these steps to resolve the “can not type in Minicom” issue:

Solution 1: Check Minicom Configuration

First, let’s check the Minicom configuration. Open Minicom and press Ctrl+A to access the configuration menu. Then, press Z to select the “Save setup as dfl” option. This will save the current configuration as the default.

  +-----------------------------------------------------------------------+
  |                          Minicom Configuration                         |
  +-----------------------------------------------------------------------+
  | A -    Serial Device      : /dev/ttyUSB0                                 |
  | B - Lockfiles Location    : /var/lock                                  |
  | C -   Callin Program      :                                           |
  | D -  Callout Program      :                                           |
  | E -    Bps/Par/Bits       : 9600 8N1                                    |
  | F - Hardware Flow Control : No                                          |
  | G - Software Flow Control : No                                          |
  |    Change which setting?                                                 |
  +-----------------------------------------------------------------------+
  | Enter your choice (A-G): Z                                              |

Solution 2: Verify Serial Port Settings

Next, let’s check the serial port settings. Use the stty command to display the serial port settings:

  $ stty -F /dev/ttyUSB0
  speed 9600 baud; rows 0; columns 0; line = 0;
  intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
  eol2 = <undef>; PK = <undef>; uk = <undef>;
  -parity -cmacrnl

Check the baud rate, data bits, parity, and stop bits to ensure they match the device’s settings.

Solution 3: Adjust Keyboard Layout and Language Settings

Incorrect keyboard layouts or language settings can cause typing issues. Check your system’s keyboard layout and language settings to ensure they match your keyboard layout and language.

In Linux, you can use the setxkbmap command to set the keyboard layout:

  $ setxkbmap us

Replace “us” with your desired keyboard layout (e.g., “us”, “uk”, “fr”, etc.).

Solution 4: Check Terminal Emulation

Terminal emulation settings can affect input in Minicom. Check the terminal emulation settings by pressing Ctrl+A and then T. This will display the terminal emulation settings:

  +-----------------------------------------------------------------------+
  |                          Minicom Terminal Emulation                    |
  +-----------------------------------------------------------------------+
  | A - VT100compatible                                                   |
  | B - VT220compatible                                                   |
  | C - ANSIcompatible                                                     |
  | D - TTYcompatible                                                       |
  |    Change which setting?                                                 |
  +-----------------------------------------------------------------------+
  | Enter your choice (A-D):                                                 |

Select the correct terminal emulation setting for your device.

Solution 5: Check Permissions and Ownership

Insufficient permissions or incorrect ownership of the serial port can prevent typing in Minicom. Check the permissions and ownership of the serial port:

  $ ls -l /dev/ttyUSB0
  crw-rw-r-- 1 root dialout 188, 0 Mar 12 14:30 /dev/ttyUSB0

If the ownership or permissions are incorrect, use the chmod and chown commands to adjust them:

  $ sudo chmod 666 /dev/ttyUSB0
  $ sudo chown username:dialout /dev/ttyUSB0

Replace “username” with your actual username and “dialout” with the correct group.

Troubleshooting Tips and Tricks

Here are some additional tips and tricks to help you troubleshoot the “can not type in Minicom” issue:

• Use the correct serial device: Ensure you’re using the correct serial device (e.g., /dev/ttyUSB0, /dev/ttyS0, etc.).
