- When transferring in one direction, its very much up to the kind of
- data you transmit. If both connect at 14,400 with BTLZ compression,
- who knows which is faster. I suspect that V.32bis is faster, but I
- haven't tested it.

- When transferring in both directions HST is no match for V.32bis. HST
- can only achieve high speed in one direction at a time, whereas
- V.32bis has 14,400 both ways. This can be felt when using the modem,
- too, as HST sometimes feels slow in response. This is due to reversal
- overhead, i.e. only one way transmits fast so sometimes the HST has to
- switch over so that the other end is fast.
