- That's because the cache remembers which blocks have been read and stores a
- copy of them in a faster storage media to reduce the need to re-read the same
- data. I am unaware of any modem which offers that level of intelligence; even
- your beloved 1024 byte buffers don't (they pass the data on one byte at a
- time, like everybody else, but have big bladders so that can go longer
- between peeing sessions).

- Show me your 14400 bps sending my choice of .ZIP file at better than 1700 CPS.

- It has nothing to do with the serial port or the operator, it has to do with
- compressability of the data. Even a 1200 bps connection can reach 10,000 CPS
- on a file of spaces... but who'd want to, except for an liar out to mislead
- others?!?

- Oops, I forgot who I was talking to.
