DH>What is the recommended setting for the %C attribute for a
DH>mailer/BBS?
        Leave it at the normal default (%c3 on modern units),
        so data compression and error correction are enabled.
        There is an exception to this.  If you are transferring
        SMALL data volumes per session (under 1k, and best if
        under 256 bytes) and you're using a solid protocol (Z-Modem
        or something equal), I would suggest FORCING a 2400bps
        non-error correcting connection when calling long-distance
        (esp. if you have 6 second billing).  The reason if that
        it takes several seconds to hand-shake for V.32/bis, VFC
        and V34, and a couple of extra seconds to setup error
        correction (call it 25 seconds of wasted billing time, 
        which is likely padding a little).  With a 2400 (240cps)
        non-error correcting connection the setup time and
        the time required to move 1k of data should be under
        20 seconds...may be under 12 seconds if all goes well.
        If you're moving larger data volumes (say anything over
        5k), then the raw carrier speed and compression are in
        your favor to use...5k of average text on a 33.6k carrier
        with a 115.2k serial port rate should take less than 1
        second to transfer.
