What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?

Please provide any additional information below.
The 4 byte buffer on Pic-UART is very poor, it causes very slow speed for
bulk transfers on binary modes (applications need to send 4 bytes and read
4 bytes overheading a simple bulk transfer). A great speed gain can be
performed by adding a 4096 software buffer.

I think this should be a topic in the development forum so the community can discuss it and offer suggestions. The main issue is how to control it. What is the use scenario? Do we just wait for 4096 bytes? A new protocol with large packet sizes? Bump bytes on an interrupt? And if so, that about the other features that might use that ring buffer at the same time (sniffers)? And what about output bytes? Do they get buffered too?
