Status Registers & Result Codes
Register Dec. Function & Description Default
S0= 0 - 255 Set the number of the rings required before the modem
automatically answers a call. Set “S0=0” to disable auto-
answer mode.
000
S1= 0 - 255 Count the incoming rings and store the value to this register.
The value of this register is incremented with each ring. If no
rings occur over an 8 sec. interval, this register is cleared.
User can read but should not change this value.
000
S2= 0 - 255 S2 holds the decimal value of the ASCII character used as
the escape character. The default value (043) corresponds to
an ASCII character “+”. A value of 128 to 255 disables the
escape process, i.e., no escape character will be recognized.
043
S3= 0 - 127 Hold the decimal value of the Carriage Return <CR>
character used as the command line and result code
terminator. Pertain to asynchronous operation only.
013
S4= 0 - 127 Hold the decimal value of the character recognized as a line
feed. The line feed control character is output after the
carriage return control character if verbose result code are
used.
010
S5= 0 - 32,
127
Hold the decimal value of the character recognized as a
backspace. The modem will not recognize the backspace
character if this register is set to a value greater than 32.
008
S6= Set the length of time, in seconds, that the modem must wait
(minimum 2 seconds even if the value is less than 2) after
going off-hook before dialing the first digit of the telephone
number.
2 - 65 For international version. 002
4 - 65 For Japanese version. 004
S7= Set the time, in seconds, that the modem must wait before
hanging up because carrier is not detected.
1 - 255 For international version. 050
35 - 59 For Japanese version. 050
S8= 0 - 65 Set the time, in seconds, that the modem must pause when
the “,” dial modifier is encountered in the dial string.
002
S10= 1 - 255 Set the length of time, in tenths of a second, that the modem
waits before hanging up after a loss of carrier.
020
S11= 50 - 150 DTMF duration and inter digit delay. Set the duration and
spacing, in mini-seconds, in DTMF touch tine dialing.
095
S12= 0 - 255 Define the maximum period, in 2-hundredths of a second,
allowed between consecutive asynchronous escape character
“+” (plus) for the escape sequence to be considered valid.
050
S28= 0 - 255 V.34 modulation en-/disabler. 0: disabled. 1- 255: enabled. 001
S30= 0 - 90 Inactivity timer. Set the length of time, in minutes, that the
modem counts when there is no data flow in or out the DTE
serial port. A connection is disengaged when the counter
reaches the preset value. Set S30 =0 to disable the inactivity
timer. For buffer mode only.
000
S36= Negotiation fallback options. 007
