PART IV: S Registers
Register S0: Auto Answer Ring.
Assigning a value from 1 to 255 in Register S0 tells the
modem the number of rings that must occur before it
can automatically answer incoming calls. The default
value = 0 (no Auto Answer).
Register S1: Count Incoming Rings.
The S1 register records the number of incoming rings.
Reset to 0 after 8 seconds of no ring.
Register S2: Value of the Escape Character.
Register S2 sets the ASCII value in decimal of the
escape character. The default value (decimal 43) is
equivalent to the ASCII character '+'.
You can change this register to any value from 0 to 255.
Values greater than 127 disable the escape feature.
Register S3: Value of the Carriage Return Character.
Register S3 sets the ASCII value in decimal of the
carriage return character (End-Of-Line). The default
value is 13. You can change it to any ASCII value
between 0 and 127.
Register S4: Value of the Line Feed Character.
Register S4 sets the ASCII value in decimal of the line
feed character. The default value is 10. You can change
it to any ASCII value between 0 and 127. If you do not
want to receive a line feed character, you can change
the value in this register to a null character, but you
cannot disable line feed characters.
Register S5: Value of the Backspace Character
Register S5 sets the ASCII value in decimal of the
backspace character. This character is the character
created by pressing BACKSPACE key and the
characters echo to host are BACKSPACE, SPACE,
BACKSPACE ( i.e. move the cursor to the left ). The
default value is 8. You can change it to any ASCII value
between 0 and 32, or 127.
Note: Do not set the value of the backspace character
between 33 and 126.
Register S6: Dial Tone Wait Time.
Register S6 sets the time to wait after going off-hook
before dialing the first digit in a Dial command when
using the X0, X1 or X3 responses. The default time is 2
seconds, although you can change it to any value
between 2 and 255 seconds. This feature is convenient
when it takes longer than 2 seconds to obtain a dial tone.
Register S7: Remote Carrier Signal Wait Time.
Register S7 decides how many seconds to wait for a
remote modem's carrier signal before hanging up. The
default value is 60 seconds. You can change it to a value
between 1 and 255 seconds. Register S7 also controls
the time-out of the W command.
Register S8: Pause Time for Comma
Register S8 decides how many seconds to pause for
each comma ( , ) encountered in a Dial command line.
You usually use the comma when dialing through a PBX
or other special telephone services to wait for an outside
telephone line. The default value is 2 seconds, although
you can change it to a value between 0 and 255
seconds. An alternative to changing this register is to
include more than one comma in your command line.
Register S9: Carrier Detect Response Time.
Register S9 sets the time the remote modem's carrier
signal must be present for the local modem to recognize
it. This feature ensures that your modem does not
mistake a busy signal, ring, or voice for the carrier
signal. The value of this register is in tenths of a second.
The default value is 600 ms , although you can change it
from 1 to 255. For example, entering a value 13 means
that the remote modem's carrier signal must be present
for 1.3 seconds for the local modem to recognize it.
Setting this value higher increases the chances the
modem will not mistakenly identify the carrier signal.
Register S10: Carrier Loss Time.
Register S10 sets the time between the loss of a remote
modem's carrier signal and when the local modem
disconnects. This allows the remote modem's carrier
signal to momentarily disappear from the telephone line.
The value of this register is in tenths of a second. The
default value is 1.4 seconds, although you can change it
from 1 to 255. You may want to set this value higher if
you have a noisy telephone line that might interfere with
