3.3.12 ATSn
S-Register Settings
Commands that begin with the letter “S” are known as “S-Parameters”. The number
following the “S” indicates the “parameter number “ being referenced. If the number is
not recognized as a valid parameter number, an ERROR result code is issued.
Immediately following this number, either a “?” or “=” character must appear. “?” is
used to read the current value of the indicated S-Parameter; “=” is used to set the S-
parameter to a new value.
S<parameter_number>?
= Read the current value.
S<parameter_number>=[value]
= Set to [value].
If the “=” is used, the new value to be stored in the S-parameter is specified in
decimal following the “=”. If no value is given (i.e., the end of the command line
occurs or the next command follows immediately), the S-parameter specified may be
set to 0, or an ERROR result code issued and the stored value left unchanged. The
ranges of acceptable values are given in the description of each S-parameter.
If the “?” is used, the modem transmits a single line of information text to the DTE.
The text portion of this information text consists of exactly three characters, giving the
value of the S-parameter in decimal, with leading zeroes included.
3.3.13 ATVn
Result Code Form
This command selects the sending of short-form or long-form result codes to the
DTE. The parameter, if valid, is written to S-Register S42.
ATV0
Enables short-form (terse) result codes. Line feed is not issued before
a short-form result code.
ATV1
Enables long-form (verbose) result codes. (Default.) Result is
presented as text (default).
3.3.14 ATWn
Enable ISDN Result Codes
This command, in conjunction with AT%Wn and AT%Vn commands can be written
directly by the host and control the formats of the extended ISDN messages (see
Section 5 and Tables at 5.2). The actual result code messages reported reflect the W
command setting and the AT%Wn and AT%Vn settings. The W parameter value, if
valid, is written to S45 bits 0 to 3.
ATW0
Result is presented without <xx> and <nr>
(default)
<xx> = ISDN error cause (see also section 5.2)
<nr> = calling party number (see also section 5.2)
ATW1
Result is presented with <xx> and <nr>
<xx> = ISDN error cause [decimal] (see also section 5.2)
<nr> = calling party number (see also section 5.2)
ATW2
Result is presented with <xx> and <nr>
<xx> = ISDN error cause [text format] (see also section 5.2)
<nr> = calling party number (see also section 5.2)
ATW3
same as ATW2 but <nr> at CONNECT message is
replaced with <datetime> element of L3 frame.
