If the port list is empty, the issue likely resides deeper, such as a faulty USB port, a damaged cable, or an improperly seated driver. If the baud rate in your code does not match the baud rate selected in your terminal software or IDE, the data will appear as garbled characters, rendering debugging impossible.
Com Port Setup Serial Communication Test: Verifying Your Configuration
Closing all other software that might be using the port is the simplest solution. A misconfigured port can lead to frustrating errors, failed uploads, and data corruption, halting a project in its tracks before any code is even written.
Once connected, the operating system will usually attempt to locate a driver. Most operating systems will prevent this access, resulting in an error.
