Nokia 6090 AT Command Set 5
Introduction
This document describes the AT commands supported by the Nokia 6090 and their
associated parameters. A short description, the syntax, the setting values and
responses of the AT commands are presented. An example of use is also provided
when relevant.
Sending a command or a parameter that is not supported by the Nokia 6090 causes
an error response.
Computers use AT commands to communicate with modems. Most communications
applications, however, have a user-friendly interface that hides AT commands from
the user. You issue AT commands via your communications application. When the
software in the Nokia 6090 has received an AT command, it responds with a
message that is displayed on the screen of the device you are using.
Note that the "AT"or "at"prefix must be included at the beginning of each command
line.

Nokia 6090 AT Command Set 6
Supported Standards
All mandatory ITU-T V.25ter, ETSI GSM 07.07, and ETSI GSM 07.05 commands,
together with optional commands applicable to the Nokia 6090, are included in this
document. Also included are de facto commands widely used among modems, and
commands specific to the Nokia 6090. Note that V.25ter is a combination of three TIA
standards (TIA-602, TIA-615, IS-131).
Some voice commands from TIA-695 (formerly known as PN-3131 and IS-101) are
supported by the Nokia 6090.
Three different fax command sets are supported. These are class 1 (TIA-578-A),
class 2 (TIA SP-2388) and class 2.0 (TIA-592 or ITU-T T.32).
NOTE: This document is intended to provide an overview and brief description of
each command supported by the Nokia 6090.. Further details can be found by
referring to the respective command source documents indicated below:

Nokia 6090 AT Command Set 8
AT Command Syntax
Note that the "AT"or "at"prefix must be included at the beginning of each command
line. Several AT commands may be typed on the same line. In such cases, it is only
necessary to type the "AT" or "at" prefix at the beginning of each command line.
Angled brackets (e.g. <n>) are used in command syntax is the setting value typed in
as a part of the command. If the value is optional, it is enclosed into square brackets.
When you select a setting value with an AT command, the setting is valid until you
change it.
Command Line
See figure below for general structure of a command line.
Basic structure of a command line
(ETSI, GSM 07.07 version 5.4.0, chapter 4.1.)
Standardised basic commands are found only in V.25ter. GSM commands use
syntax rules of extended commands. Every extended command has a test command
(=?) to test the existence of the command and to give information about the type of
its subparameters. Parameter type commands also have a read command (?) to
check the current values of subparameters. Action type commands do not store the
values of any of their possible subparameters, and therefore do not have a read
command.
If verbose responses are enabled with command V1 (see page 64) and all
commands in a command line have been performed successfully, result code
<CR><LF>OK<CR><LF> is sent from the TA to the TE. If numeric responses are
enabled with command V0 (see page 64), result code 0<CR> is sent instead.
If verbose responses are enabled with command V1 and subparameters values of a
command are not accepted by the TA (or command itself is invalid, or command
cannot be performed for some reason), result code <CR><LF>ERROR<CR><LF> is
sent to the TE and no subsequent commands in the command line are processed. If
numeric responses are enabled with command V0, result code 4<CR> is sent
instead. ERROR (or 4) response may be replaced by +CME ERROR: <err> or +CMS
ERROR: <err> when the command was not processed due to an error related to ME
or network operation.

Nokia 6090 AT Command Set 9
Information Responses and Result Codes
The TA response for the example command line in the figure above could be as
shown below. Here, the verbose response format is enabled with command V1 (see
page 64). If numeric format V0 had been used, the <CR><LF> information response
headers would have been left out and final result code would appear as 0<CR>.
Response to a command line
(ETSI, GSM 07.07 version 5.4.0, chapter 4.2.)
So-called intermediate result codes inform about progress of TA operation (e.g.
connection establishment CONNECT), and so-called unsolicited result codes indicate
occurrence of an event not directly associated with commands issued by the TE
(e.g. ring indication RING).
Command Line and Response Formatting Commands
The table below summarises the commands relating to command line and response
formatting. All are applicable to GSM terminals.
Command Description
S3=<value> command line termination character
S4=<value> response formatting character
S5=<value> command line editing character
E<value> command echo
Q<value> result code suppression
V<value> TA response format
X<value> defines CONNECT result code format;
values manufacturer specific
+CMEE=<n> ME error reporting control

Nokia 6090 AT Command Set 10
AT Commands for Nokia 6090
In alphabetical order (with description)
A/ Repeat Last Command Line
A/ can be used as the first characters in a command line replacing normal AT. Also
lowercase (a/) accepted. (V.25ter)
? Help
Returns information about implemented AT commands.
The Help command returns with the response:
“AT" or "at" prefix must be included at the beginning of each command line.
It is possible to type several AT commands on the same command line. In such
cases, it is only necessary to type the "AT" or "at" command once at the beginning of
each command line.
Syntax of AT+ Commands
To select, display or assign a value for a setting, type in AT+
the command string followed by "=n", "?", or "=?", and press <ENTER>:
•AT<+command>=n to write in a new setting with the command.
•AT<+command>? displays the current setting for the command
•AT<+command>=? displays all possible setting values that can be used with the
command.
&C Define DCD Usage [circuit 109 (RLSD) behaviour]
This command determines how the state of the DCD V.24 signal relates to the
detection on received line signal from the distant end. (V.25ter.)
Syntax:
AT&C[0] Keep DCD always ON.
AT&C1 Enable normal DCD usage. Default
option.
&D Define DTR Usage [circuit 108 (DTR) behaviour]
This command defines how the DTR V.24 signal from the DTE is handled. Command
&Q effect is present. (V.25ter.)
Syntax:
AT&D[0] DTR is ignored if &Q0 is selected. DTR
ON-OFF hangs up call if &Q2 is selected.
(&Q effect is a de facto feature.)
AT&D1 DTR ON-OFF causes a transition to on-
line command state, if there is call in
progress.
AT&D2 DTR ON-OFF hangs up the call. Default
option.
AT&D3 DTR ON-OFF hangs up the call and
resets the data parameters to the start-up
values (like command Z). This is a de
facto feature.

Nokia 6090 AT Command Set 11
&F Restore Factory Settings
This command restores all the factory settings including all the S-register settings but
does not save them. Command parameters that are reset to their factory defaults are:

AT&K[0] Disable flow control.
AT&K3 Set hardware flow control (CTS/RTS).
Default option.
AT&K4 Set software flow control (XON/XOFF)
&Q Define Communications Mode Option
This command defines the dialling and on-line options. (De facto.)
Syntax:
AT&Q[0] Enable normal asynchronous operation.
Default option.
AT&Q2 Enable DTR controlled dial. DTR OFF to
ON causes a call to be made to the
number stored in the TA dial slot zero.
DTR ON to OFF hangs up the call.
&S Define DSR Option
This command defines how the DSR V.24 signal is handled. (De facto.)
Syntax:
AT&S[0] Keep DSR always ON.
AT&S1 Enable normal DSR usage. Default
option.
&V View Active Configuration
This command displays the current values of the S-registers. (V.25ter)
Syntax:
AT&V[0] View active configuration. (All command
parameter values defined under &F and
&Y settings).
AT&V1 Show settings in stored profile 0. (All
command parameter values defined under
&W).
AT&V2 Show settings in stored profile 1. (All
command parameter values defined under
&W).
Response is for V1 and V2:
E1 Q0 V1 X5 &C1 &D2 &Q0 &S1
S00:000 S01:000 S02:043 S03:013 S04:010 S05:008 S07:060 S08:002

S45:006 S46:000 S47:000 S48:000

Nokia 6090 AT Command Set 12
&W Store Configuration
This command stores the current settings to one of two user profiles. Command
parameters that are stored to a profile are the same as listed under the command &F
(see page 11) except the parameters of the following commands which are not
stored: +CMOD, +CSCA, +CSMP. (De facto.)
Syntax:
AT&W[0] Store settings to user profile 0.
AT&W1 Store settings to user profile 1.
Please note that AT&W is not supported so as to save previously used baudrate.
Appropriate AT command to set the baudrate has to be sent each time the Nokia
6090 is started.
The Antenna Motor Control line (AMC) can give an indication to an external device
that the 6090 is powered on, then the device can send the appropriate AT-command
in order the Nokia 6090 to switch to 9600 bps again.
&Y Select Power-Up Configuration
This command defines from which user profile (0 or 1) parameters are loaded when
the Nokia 6090 is activated. This setting is not included in the settings that are stored
in a user profile. The command &F does not affect this setting. (De facto.)
Syntax:
AT&Y[0] Parameters are loaded from user profile 0.
AT&Y1 Parameters are loaded from user profile 1.
+++ Escape
During on-line data state, the online command state can be entered by giving three
same characters in a sequence. The character is defined by S-register S2. The
default character is '+'. Before and after the sequence there must be a pause of at
least the time defined by S-register S12. By setting S12 to zero, escape sequence
detection can be disabled. (De facto.)
Syntax:
+++ Enter on-line command state.
'+' is default character.

Nokia 6090 AT Command Set 13
+CALA Alarm
Sets and reads the alarm in the ME. If <type> indicates a daily alarm time, only hour
and minute fields of <time> are used (in responses, rest are set to zero). Time zone
is not supported, and it is ignored when 'set' command is used, and 'read' command
does not return the time zone characters in <time>. Disabled alarms are not returned
by 'read' command. (GSM 07.07.)
Syntax:
AT+CALA=<time>[,<n>[, <type>]] Default option is [,1,0].
AT+CALA? Query current setting.
Response is +CALA: [<time>,0,1]
AT+CALA=? Show supported values. Response is
+CALA: (1), (list of supported <type>'s),
(0)
Parameters:
<time>: refer to command +CCLK (see page 16)
<n>: integer type value indicating index of alarm

connection element <ce> to be used when data calls are originated (GSM 02.02).
Values may also be used during mobile terminated data call setup, especially in case
of single numbering scheme calls (see the command +CSNS, page 48). Test
command returns values supported by the TA as compound values. (GSM 07.07)
Syntax:
AT+CBST=[<speed>[, <name>[, <ce>]]] Select bearer service type. Default
option is 0, 0, 1.
AT+CBST? Query current setting.
Response is +CBST: <speed>, <name>,
<ce>
AT+CBST=? Show supported values.
Response is +CBST: (list of supported
<speed>'s), (list of supported <name>'s),
(list of supported <ce>'s)
Parameters:
<speed>:
0autobauding (automatic selection of the
speed; this setting is possible in case of
3.1 kHz modem and non-transparent
service)
1300 bps (V.21)
21200 bps (V.22)
31200/75 bps (V.23)
42400 bps (V.22bis)

64800 bps (V.32)
79600 bps (V.32)
65 300 bps (V.110)
66 1200 bps (V.110)
68 2400 bps (V.110 or X.31 flag stuffing)
70 4800 bps (V.110 or X.31 flag stuffing)
71 9600 bps (V.110 or X.31 flag stuffing)
<name>:
0data circuit asynchronous (UDI or 3.1 kHz
modem)
2PAD Access (asynchronous) (UDI)
<ce>:
0transparent
1non-transparent
2both, transparent preferred
3both, non-transparent preferred
Note: The <name> parameter '2' can only be used, in combination with valid <speed>
and <ce> parameters.
Certain combinations with <name>= 2 are not allowed. For example, if the settings
were at+cbst=0,0,1 and you set after this at+cbst=0,2,1 . The ME will return "Error"
because the setting at+cbst=0,2,1 is not allowed.
The parameter shall be used in an appropriate context. i.e. at+cbst=66,2,1, is
accepted.

Nokia 6090 AT Command Set 15
+CCFC Call Forwarding Number and Conditions
This commands allows control of the call forwarding supplementary service according
to GSM 02.82.. <reason> values 4 and 5 are only applicable for <mode>=0. When
status request response from network indicates that SS is active for specific data
bearer services (e.g. 'circuit async'), AT interface indicates only 'data' (<class>=2)
('not active' case is displayed only when SS is not active to any service; i.e. +CCFC:
0,7). (GSM 07.07)
Syntax:
AT+CCFC=<reason>,
<mode>[,<number>
[,<type>[,<class>
[,<subaddr>
[,<satype>[, <time>]]]]]
When <mode>=2 the response is +CCFC:
<status>,<class1>[,<number>,<type>
[,<subaddr>,<satype>[,<time>]]]
[<CR><LF>+CCFC:
<status>,<class2>[,<number>
,<type>[,<subaddr>,<satype>[,<time>]]]
[...]].
Default option is [,,, 129/145,7 ,,128,20]
AT+CCFC=? Show supported <reason>’s.
Parameters:
<reason>:
0unconditional
1mobile busy
2no reply
3not reachable
4all call forwarding (GSM 02.30)
5all conditional call forwarding (GSM 02.30)
<mode>:
0disable
1enable
2query status
3registration
4erasure
<number>: string type phone number of forwarding address in format specified by
<type>
<type>: type of address octet in integer format (GSM 04.08); default 145 when
dialling string includes international access code character "+", otherwise 129
<class> is a sum of integers each representing a class of information (default 7
equals to all classes):
1voice
2data
4fax
also all other values below 128 are reserved
<subaddr>: string type subaddress of format specified by <satype>
<satype>: type of subaddress octet in integer format (GSM 04.08), default 128
<time>: 1...30 when "no reply" is enabled or queried, this gives the time in seconds
to wait before call is forwarded, default value 20
<status>:
0not active
1active
Examples:
AT+CCFC=1,2
Queries the status of “mobile busy” (i.e. the mobile is on, a call is active but the
user/network turned off the “Call waiting service”)
Response:
+CCFC: 1,1,"[phone] ",145

Nokia 6090 AT Command Set 16
The first number is the status (here: on), the second is classx (here: voice) and the
international number to which the call forwarding for this case (here:
[phone]).
AT+CCFC=2,2
Queries the status of “no reply” (i.e. the mobile is on but the user does not answer the
call) and displays the settings.
AT+CCFC=3,2
Queries the status of “not reachable” (i.e. the mobile is out of network range) and
displays the settings.
AT+CCFC=0,2
Queries the status of “unconditional” (i.e.all other reasons and/or all calls) and
displays the settings.
Response:
+CCFC: 1,4,"[phone]",145
Same number as above, but here the classx is fax only.
AT+CCFC=0,0
Disables the call forwarding for the reason “unconditional”.
AT+CCFC=0,2
Response:
+CCFC: 0,7
Nothing is set.
Now we set it to the state as before:
AT+CCFC=0,3,"[phone]",145,4
AT+CCFC=2,3,"[phone]",145,7,,,20
This forwards “no reply” for all class after 20sec to the above number.
Response:
+CCFC: 1,1,"[phone]",145
+CCFC: 1,2,"[phone]",145
This shows only voice and data, because fax was set via “unconditional” and “no
response” consequently does not apply.
All of the above combinations are very network dependent. Ask your network
operator if you have the rights to set forwardings, which won't work, for you.
+CCLK Clock
Sets and reads the real time clock of ME. Time zone is not supported, and it is
ignored when 'set' command is used (but must be given), and 'read' command does
not return the time zone characters in <time>. (GSM 07.07)
Syntax:
AT+CCLK=<time>
AT+CCLK? Query current setting.
Response is +CCLK: <time>.
AT+CCLK=? OK

Nokia 6090 AT Command Set 18
<number>: string type phone number of calling address in format specified by
<type>
<type>: type of address octet in integer format (GSM 04.08)
<alpha>: optional string type alphanumeric representation of <number>
corresponding to the entry found in phonebook; used character set should be the one
selected with command Select TE Character Set +CSCS
Examples:
AT+CCWA=1,2
Queries the status of the “Call waiting service”
AT+CCWA=1,1,4
Set call waiting for fax only.
AT+CCWA=0,0,2
Disables call waiting for fax only.
AT+CCWA=1,1
Sets call waiting for voice, fax and data.
AT+CCWA=0,0
Disables the “Call waiting service”
All of the above combinations are very network dependent. Ask your network
operator if you have the rights to set forwardings that wouldn’t work for you.
If call waiting is active, you are doing a call and you are called you might see:
+CCWA: "",145,1
Alternatively, you may see the callers number:.
+CCWA: "[phone]",145,1
Now you could change active calls with the +CHLD command.
+CEER Extended Error Report
This command causes the Nokia 6090 to return one or more lines of information text,
which should offer the user an extended report of the reason for failure in the last
unsuccessful call setup (originating or answering). Typically, the text will consist of a
single line containing the failure information given by the GSM network in a textual
format. <report> is the textual representation of network cause value as listed in
GSM 04.08 annex H. (GSM 07.07)
Syntax:
AT+CEER Display error report.
Response is +CEER: <report>
AT+CEER=? OK
<report>: the total number of characters, including line terminators, in the information
text do not exceed 2041 characters. Text does not contain the sequence 0<CR> or
OK<CR>.
