You're probably thinking about end to end TCP over a datagram cloud.
That works, of course, that's the Internet.  I was talking about TCP
from A to B, raw UART B to C, TCP from C to D.  TCP wouldn't be
helping you detect or correct data loss on the B to C path, and that
means you'd need application layer acks (as in the current remote GDB
protocol) for that case.  But that's a topology that makes no sense to
me and I wouldn't expect ever to see.
