HUH?

    That means:
1.  I can't use a Telebit modem's uucp spoofing because the modem
    has to do pep for it to work, but that pep is an error correcting
    protocol done by the modem.  Right?

2.  That the uucp transfers that have been happening the last six
    months wern't really happening, and all those bits are on the
    floor behind my computer?

3.  You made a mistake in the chart, and I am responding before the
    corrected one comes out.

Which choice?

Jim
