RC| Partly.  Error correction also requires a higher port speed than

8 bits/byte of original data plus some CRC overhead, actually.
Yeah, Rick, I know.  But I was responding to somebody complaining
that Telix didn't have a setting for a 14.4kbps modem.  I figured he
didn't need all the details, just the concept that the modem is
sending out a more compact data stream than it receives from the
computer.  This stuff is confusing enough on first hearing as it is.
