Transfer
of
a
Modem
Session
Because
many
modem
command
variations
exist,
the
sample
modem
configuration
files
located
at
the
end
of
this
appendix
have
been
written
to
capture
the
largest
number
of
workable
modem
settings.
The
modem
command
&Dn
(where
n
is
a
number)
generally
sets
the
modem
response
to
the
Data
Terminal
Ready
(DTR)
signal
from
the
server’s
serial
port.
The
desired
response
is
that
the
modem
will
hold
a
connection
while
DTR
is
enabled,
and
drop
the
connection
when
DTR
is
released.
Using
this
mechanism,
the
server
hangs
up
on
a
connection
under
normal
conditions.
Consult
your
modem
manual
for
its
specific
response
scheme
for
the
&Dn
command.
Two
strategies
are
available
for
dealing
with
the
modem’s
response
to
DTR:
v
Recovery
v
Prevention
Before
you
use
one
of
these
strategies,
determine
if
your
server’s
modem
is
set
up
correctly
to
respond
to
DTR.
With
the
remote
terminal
connected
to
serial
port
1
and
defined
as
the
Primary
Console
Device,
there
are
two
tests
you
can
perform:
v
Will
the
modem
drop
the
connection
after
the
System
initialization
complete
message
displays
at
the
remote
terminal?
If
Yes,
the
modem
is
set
up
correctly.
If
No,
try
another
&Dn
setting
for
your
server’s
modem.
See
your
modem
manual
for
this
information.
The
&Dn
command
appears
in
three
places
each
in
three
of
the
sample
modem
configuration
files,
as
follows:
v
Will
the
server’s
modem
disconnect
when
the
power
drops?
You
can
make
this
observation
at
the
remote
terminal
by
commanding
your
server
to
shut
down
and
power
off.
(Use
the
AIX
command
shutdown
-F
.)
Watch
for
the
message
NO
CARRIER
on
your
remote
terminal.
If
Yes,
this
is
the
correct
response.
The
modem
is
set
up
correctly.
If
No,
try
another
&Dn
setting
for
your
server’s
modem.
See
your
model
manual
for
this
information.
The
&Dn
command
appears
in
three
places
each
in
three
of
the
sample
modem
configuration
files.
Only
the
following
sample
modem
configuration
files
contain
the
&Dn
command
(in
three
places
each):
–
modem_f.cfg
–
modem_f0.cfg
–
modem_f1.cfg
If
you
are
using
modem_z.cfg
or
modem_z0.cfg,
you
cannot
control
DTR
response.
If
your
remote
terminal
does
not
disconnect
after
logging
off,
you
must
command
the
remote
terminal
emulator
to
hang
up.
This
then
breaks
the
connection.
