Troubleshooting Minicom Send Commands on Linux-based PC

The ability to communicate with devices connected via serial ports is essential in various applications, including embedded systems programming. In this scenario, we are dealing with a ChipSHOUTER device that requires specific settings and configurations for seamless communication using minicom. However, the challenge lies in configuring minicom correctly to recognize and respond to commands.

As observed during troubleshooting, Linux-based PCs use only a line feed (0x0A) as the termination character, which is not compatible with minicom or PuTTY. This limitation necessitates the use of alternative applications that allow specifying the termination character for input. Cutecom, in particular, stands out due to its unique feature of enabling users to specify the termination character.

To date, only two applications have been found to work successfully on our Linux-based PC: the shouter-console.py script and cutecom. The python-based serial console port script within the ChipShouter git repository (shouter-console.py) has also proven effective. This highlights the importance of using compatible applications that cater to specific requirements.

In this context, we are interested in exploring why minicom cannot be used as an alternative to the shouter-console.py script for communicating with the ChipSHOUTER. Despite having the correct serial port settings (115,200 baud 8N1) and configuring minicom accordingly, it appears that any commands entered after hitting the Carriage Return are not recognized by the device.

The minicom application consistently displays the help menu, regardless of the input provided. This suggests that the configuration settings for minicom might not be adequate to accommodate the specific requirements of the ChipSHOUTER.

To overcome this challenge, further investigation is necessary to determine the correct settings for minicom that would enable successful communication with the ChipSHOUTER. In light of our experience with alternative applications, we are confident that finding a compatible configuration will allow us to utilize minicom effectively.

We encourage readers who have successfully used minicom or other Linux terminal emulation applications with similar requirements to share their experiences and insights. Your input is invaluable in helping us resolve this issue and explore potential solutions for communicating with the ChipSHOUTER using minicom.
