Anyone know of a U(S)ART that is register compatible with a 16450/16550 that is also capable of handling synchronous transmission/reception? I have designed a card that can talk x.21 to an NTU (same as a CSU/DSU) using the 16550, but it would be nice if i didn't have to put quite so much glue logic on the board.
