Can you provide logs? And how are you running these attempts?

Can you provide logs?

Sure, but they'll just show the response being null half of the time.

And how are you running these attempts?

Directly through sample.html, so nothing besides the standard MT Scale testing.

When I rewrote the serial classes I wasn't aware messages could be split over multiple receives.
315a17c fixes that with a byte buffer that will return complete messages as it receives them.
