Bimodem

    Bimodem is a great  external  protocol,   which allows  a  user to
    download,  upload and chat to the sysop  all at the same time.

    This  obviously  is of great benefit  to the sysop  and the  user,
    however there  are quite a few problems  putting  it into  effect.

    One  of these problems is getting RA to log uploads  and downloads
    when a  user does both during a bimodem session.   For this reason
    running Bimodem  as a 'External Protocol' directly from RA is does
    not produce perfect results.    There are  a few  great  utilities
    for  interfacing RA with Bimodem.   Two examples of such a program
    are 'QKBIR21A.ZIP' and 'RABIM421.ZIP'.
