Function & Description
Set the number of the rings required before the modem
automatically answers a call. Set "S0=0" to disable auto-
answer mode.
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.
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.
Hold the decimal value of the Carriage Return <CR>
character used as the command line and result code
terminator. Pertain to asynchronous operation only.
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.
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.
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.
For international version.
For Japanese version.
Set the time, in seconds, that the modem must wait before
hanging up because carrier is not detected.
For international version.
For Japanese version.
Set the time, in seconds, that the modem must pause when
the "," dial modifier is encountered in the dial string.
Set the length of time, in tenths of a second, that the modem
waits before hanging up after a loss of carrier.
DTMF duration and inter digit delay. Set the duration and
spacing, in mini-seconds, in DTMF touch tine dialing.
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.
V.34 modulation en-/disabler. 0: disabled. 1- 255: enabled.
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.
Negotiation fallback options.
