The low-level I/O functionsread()andwrite()do not use an I/O buffer. If the request exceeds the size of the _CIOBUF_ buffer, only the first BUFSIZ bytes will be read or written, and the return value will indicate how many bytes were read or written. Thus, if you need to write ...

In the cliOutputCallback function, the buffer size passed to vsnprintf may lead to a buffer overflow. The size parameter should reflect the remaining space in the buffer starting from the current index. Apply this diff to correct the buffer size calculation: -vsnprintf(&cliLineBuffer[cliLineBu...

Some possible reasons for data loss include buffer overflows, insufficient memory allocation, or timing issues. You may want to consider optimizing your code to reduce the amount of data being sent or increasing the buffer size to accommodate the data. Additionally, you can try using the HAL ...
