- I thought so, too, when Microcom first started promoting their DeskPorte Fast
- EP parallel port modems, but the truth is that the parallel interface provides
- byte-by-byte handshaking, i.e. automatic flow control with no lost data.

- This is a good thing in environments like Windows, where it may take a while
- to get around to signalling RTS, and when some buffered UARTs have several
- bytes loaded in their FIFOs that can't be held back even after flow control
- signal is received.
