How a request reaches the far end and its answer comes back.
exchange carries one request built by link_host_read() or link_host_write() and returns true with the answer in reply, a refusal included, or false when it ended unanswered. It leaves no request outstanding on h either way. now_ms is the millisecond clock the requests are stamped with.
between, when not NULL, is called after each acknowledged frame of a write that has another frame to send. A write of 32 registers is 8 exchanges back to back, and an exchange answered at once returns without the caller's other work having run: the panel runs its safety loop here. It is not called for a write of one frame, after the last frame, or after a refusal.
