- I heard about the 16650 UART some time ago, which has 32 byte FIFOs
- rather than 16. While it sounded interesting, it also didn't seem
- like something I "just had to have." However, now I've seen some
- specs on the 16750 UART. Got to try one of these.
-
- It seems that in addition to a 64 byte FIFO (no surprise) it will do
- the hardware handshake for you! Now the slowest system around will
- not lose data because the UART will drop RTS when the FIFO is almost
- full, and will stop sending if the CTS drops. This is where the
- logic should have been all along, and all I want to know is where to
- find one.
-
- Any experience with these? The larger buffer is nice, but the flow
- control changes the whole dynamics of how UARTs are handled.
