4.5
Speed
of
Transmission
When
the 1200 bps
internal
modem
calls
another system
it
auto-
matically detects and
adjusts to the transmission
speed (baud
rate)
at
which your
personal
computer
is
operating.
The
transmission
speed
is
thus
governed by
the device you have connected
to the
modem. You
must
set
the speed
of
your computer
either
by
setting
a
switch
in
the
hardware
or
by
a
software
command.
A
command
to
the
modem
will
not change
the speed
of the
equipment.
If
the 1200
bps
internal
modem
is
in
answer mode,
it
adjusts to
the speed
of the
calling
modem. You
can use
the
X command
to
tell
the
modem
to
inform you
of the
speed
of
the
call
it is
answer-
ing.
For example,
after connection, the
result
codes would
read:
CONNECT
(for a
110
or
300 baud
connection)
or
CONNECT
1200
(for
a
1200
baud
connection)
Note
that the 1200
bps
internal
modem
will
accept
a
call
from
a
1200 baud
or a 300 baud
modem.
Your computer must be
set to
the correct baud
rate for
the
call.
When
the
modems
begin
to "talk" to
each
other,
your
1200
bps
internal
modem
will
detect the speed
of the
calling
modem
and
adjust
its
speed
to
match.
The
modem
will
then send
a
message
to
