Hi.
        I've had a problem with a Diamond 56K modem through a PBX. The
solution has been to bypass the PBX and go direct. However, in the
meanwhile, with the problems present, some diagnostic messages sent
by the modem have been:
        "DELAYED 00:40.00"
        "BLACKLISTED"
        Since the modem documentation is scarce, I'd appreciate if
someone knows the exact meaning of above messages (specially BLACKLISTED).

  Starting point:        (-1)^(-1) = -1
  Applying logarithms: (-1)*ln(-1) = ln(-1)
  Since ln(-1) <> 0, dividing:  -1 = 1     (ln(-1) is complex, but exists)
