In C you have one choice (printf), but that choice may not fit your

There are 2 buffers (RX one and TX one, both of 'reasonable' size)

Irrelevant to how you log the data.
* print content of RX-buffer, ommiting terminating '\n' ('\n' is the
'end of request') to (log/journal file)/stdout/
* ouptut received 'message' back to client, _with_ terminating '\n'
Since the data is unmodified, then you can do this too after logging it
without the `\n`. Two separate needs, both well handled by using ranges
and algorithms.
Or if they don't suit you well enough, just write your own. Writing a
wrapping range isn't hard.
