Xon/Xoff
Modems
Some
early
modems
assume
software
flow
control
(Xon/Xoff)
between
the
computer
and
the
modem.
Modems
with
this
design
send
extra
characters
during
and
after
the
transmitted
data.
The
service
processor
cannot
accept
these
extra
characters.
If
your
configuration
includes
such
a
modem,
your
functional
results
may
be
unpredictable.
The
sample
modem
configuration
files
included
in
this
appendix
do
not
support
these
modems,
so
custom
configuration
files
are
necessary.
Anchor
Automation
2400E
is
an
example
of
such
a
modem.
If
you
experience
unexplainable
performance
problems
that
may
be
due
to
Xon/Xoff
characters,
it
is
recommended
that
you
upgrade
your
modem.
