Has anyone in the modem protocol design business considered dropping
the carrier when the line is idle, and picking it up again when there
is data to be sent? Can't modems be made to recognize the difference
between on and off-hook?  This would render moot the whole 'separate
charge for modem use' issue, as modems would have the same line usage
as human voice as far as the phone company was concerned.
