It is certainly normal for most modems that you get a second or so
of noise when the far end disconnects.  A second or so is only a few
garbage characters at 2400 bps.  At 19,200 it could well be a page
or so of garbage.  It's a race between the receiver -- which is
trying to decode data from the noise, and the carrier detector,
which decides after a while that there's no more carrier, and that
the receiver can stop listening.
