S registers for the Line Link 144e
S0 Auto-answer
Range Default
0-255 rings 0 This register determines the
number to rings the modem will
count before automatically
answering a call. A value of 0 will
prevent the modem from
answering. Values from 1 thru
255 are the number of rings the
modem will count before
answering. The default value is 0.
S1 Count Incoming Rings
Range Default
0-255 rings 43 This register counts the number of
incoming rings. When the value in
this register equals the value in
Register S0, the modem answers.
This register resets approximately
8 seconds after the last ring.
S2 Escape Character
Range Default
0-127 ASCII 43 Register S2 sets the ASCII value of
the escape characters, used to
switch the modem from Data
Mode to Command Mode without
losing the connection to the
remote modem. Values greater
than 127 disable the escape
feature, preventing a return to the
Command Mode. If the modem
will be used to automatically
answer incoming calls, either
disable the escape characters of
set them to a value other than
that used by the originating
modem. To return to Command
Mode with the escape characters
disabled, the remote modem must
hang up or an ON-to-OFF
transition of the DTR interface
signal must occur with the &D1,
&D2, or &D3 command in effect.
S3 Carriage return character.
Range Default
0-127 ASCII 13 Register S3 sets the ASCII value of
the carriage return (end-of-line)
character. This is the character
used to end the command line
(and have the modem execute the
line) and also the character that
appears after the modem sends a
response.
S4 Line feed character.
Range Default
0-127 ASCII 10 Register S4 sets the ASCII value of
the line feed character. The
modem sends the line feed
character after a carriage return
only when word responds are sent
(v1command in effect). If a line
feed characters is not
wanted,change the register value
to a null character ( the line feed
character cannot be totally
disabled).
S5 Backspace character.
Range Default
0-32, 127 ASCII 8 Register S5 sets the ASCII value of
the backspace character. This
character is both the character
created by pressing the Backspace
key and the character echoed to
move the cursor to the left. To
change the register value, assign
an ASCII value between 0 and 32,
or greater than 127. Do not use
values between 33 and 126 since
they correspond to printable
ASCII characters.
S6 Wait for dial tone.
Range Default
2-255 seconds 2 When the modem executes a Dial
command line with the X0, X1, or
X3 response set in effect, Register
S6 tells the modem how long to
wait after going off hook before it
dials the first digit in the Dial
command line. This feature is
convenient when it takes linger
than two seconds to obtain a dial
tone. If the modem does not
detect a dial tone when the tome
in Register S6 elapses, you will
receive the NO DIALTONE (or 6)
response.
S7 Wait time for carrier.
Range Default
1-60 seconds 40 Register S7 tells the modem how
many seconds to wait for a remote
modem's carrier signal before
hanging up. the register value can
be increased if the modem does
not detect a carrier within the
specified time. If the modem
detects a remote carrier signal
within the specified time, it sends
a CONNECT response and enters
Data Mode. If it does not detect a
remote carrier signal within the
specified time, it sends the NO
CARRIER (or 3) response, hangs up
and returns to the Command
Mode.
S8 Pause time for comma.
Range Default
0-255 seconds 2 Register S8 tells the modem how
many seconds to pause for each
comma (,) it encounters in a Dial
command line. The comma is used
when dialing through a PBX or
other special telephone service to
wait for an outside telephone line.
An alternative to changing this
register value is to include more
than one comma in your command
line.
S9 Carrier Detect response time.
Range Default
1-255 06 Register S9 tells the modem how
1/10 seconds long the remote modem's carrier
signal must be present so the
modem does not mistake the
signal for a busy signal, ring, or
voice. The factory setting requires
the modem to listen to the carrier
signal for at least 0.6
seconds before recognizing it.
Increasing the time in this register
reduces the chances that the
modem will mistake noise such as
a busy signal or voice for a carrier
signal. For example, entering a
value 15 means that the remote
modem's carrier signal must be
present for 1.5 seconds for the
modem to recognize it.
S10 Carrier loss time.
Range Default
1-255 14 Register S10 sets the time
1/10 seconds between the loss of a remote
modem's carrier signal and when
the modem disconnects. This
allows the remote modem's carrier
signal to momentarily disappear
from the telephone line without
the modem disconnecting. the
factory setting can be changed to a
higher value when a noisy
telephone line that might interfere
with the remote modem's carrier
signal. To have the modem ignore
the Data Carrier Detect status and
act as if the remote modem' s
carrier signal is always present,
set the value to 255. Assigning a
value smaller than the value in
Register S9 causes the modem to
disconnect when it detects a
momentary carrier less, because
Register S10 expires before the
carrier response time expires.
S-Register Description
S11 Range Default
50-255 ms 75 Register S11 controls the speed of
the Touch-Tone (DTMF) dialing.
Increasing the register value to
255 slows the dialing rate to 1.9
digits per second. Do not select a
value less than 50 milliseconds.
(Register S11 has no effect on
pulse dialing, which is fixed at 10
pulses per second.)
S12 Return to data mode timer.
Range Default
0-255 1/50 seconds 40 Register S12 controls the time
delay before typing the escape
characters. Register S12 controls
the time before returning to data
mode after receiving escape
characters unless "AT" command
is received.
