About This Guide

Service InformationIf you have a problem with your equipment, contact the Symbol Support Center for your region. See page xvi for contact information. Before calling, have the model number, serial number, and several of your bar code symbols at hand.

Call the Support Center from a phone near the scanning equipment so that the service person can try to talk you through your problem. If the equipment is found to be working properly and the problem is symbol readability, the Support Center will request samples of your bar codes for analysis at our plant.

If your problem cannot be solved over the phone, you may need to return your equipment for servicing. If that is necessary, you will be given specific directions.

Note: Symbol Technologies is not responsible for any damages incurred during shipment if the approved shipping container is not used. Shipping the units improperly can possibly void the warranty. If the original shipping container was not kept, contact Symbol to have another sent to you.

Chapter 1 Introduction

The G18 integrated tri-band GSM/GPRS radio modem allows the terminal wireless connectivity using the GSM900/1800/1900 cellular networks. This guide describes the AT command set supported by this radio modem.

1-1


AT Command TablesThe following tables list the commands supported by the modem.

AT CommandsTable 1-1 and Table 1-2 list the AT commands for the modem. Most of these commands are from the V.25ter reference.

The format of the command is:

AT<command>

For example, ATE0 turns off the echo command.

Note: To repeat the previous command, use A/. This is not prefixed with AT.

Table 1-1. Basic Call Control Commands (Including V.25ter)

Command Function

A Goes off-hook and attempts to answer a call

Dn Dial modifier. For voice calls use one of the following commands:ATDxxxAT*Dxxxx ATD>102 ATD>DAN ATDS=1 ATDS=0 ATD>SM101

E0 Turns off command echo

E1 Turns on command echo

F No action, compatibility only

H Initiates a hang-up sequence

Table 1-1. Basic Call Control Commands (Including V.25ter) (continued)

Command Function

1-3


S95 Bitmap register for extended result code

S96 Echo cancelling feature for audio devices by ATS96=1

S97 Antenna diagnostic feature: ATS97? responds with 000 or 001. 000 means that either the antenna is not connected or the hardware does not support this feature.

S98 ATS98=1 allows the handset’s backlight to behave as if the unit was not powered by the TS line. It turns off the backlight immediately, for the first time after powering up. Note: ATS98=x is allowed only for x=1.

S99 ATS99=x defines the length in ms of the hardware pulse given when the GPRS coverage is changed from no coverage to coverage. The pulse length is 2x when the data indication is sent. The default value is 30 ms; 0 is not allowed. S99 responds with an error if the value is greater than 2,147,483,647 or equal to zero.

S100 ATS100=x, where x defines the number of seconds. To avoid frequent hardware interrupts, the modem uses hardware indication for data only after x seconds from the last sent character to the DTE. The default value of x is 1 second; 0 is not allowed. S100 responds with an error if the value is greater than 32,767 or equal to zero.

S101 Sets the wakeup line forever when x=1, and resets it when x=0. ATS101? returns the current state. These operations are allowed only when the factory bit is set. When the parameters are wrong, or the factory bit is not set, it returns an error.

T No action, compatibility only

V0 Reports short form (terse) result codes

V1 Reports long form (verbose) result codes

W0 Reports DTE in Error Correction (EC) mode

X0 Reports basic call progress result codes: OK, CONNECT, RING, NO CARRIER (also for busy, if enabled, and dial tone not detected), NO ANSWER, and ERROR.

X1 Reports basic call progress result codes and connection baud rates: OK, CONNECT, RING, NO CARRIER (also for busy, if enabled, and dial tone not detected), NO ANSWER, CONNECT XXXX, and ERROR.

X4 Reports all calls progress result codes and connection rates: OK, CONNECT, RING, NO CARRIER, NO ANSWER, CONNECT XXXX and ERROR

3-73


NotesWhile conducting a data call, the receipt of an SMS resets the +CNMI setting, indicating something unexpected has occurred.After automatically transferring a SMS/CBM message to the DTE (mt=2 and/or bm=2), the modem waits for a +CNMA response from the DTE (within one minute). If the DTE does not respond within this time, or if another message arrives from the network, the modem saves the message in SIM, exits from SMS mode, and sets all CNMI parameters to zero.When DTE does not respond on time for other SMS indications (E6.13.24 and above), the CNMI indication for cell broadcast messages is not cleared automatically.In the following scenario, the modem ends SMS mode and resets the CNMI parameters.This indicates that something occurred during the data call:

1 AT CNMI=0,1,0,1,0 or CNMI=0,2,0,1,0

2 MO DATA call, connected state.

3 SM received.

The G18 will end SMS mode and reset the CNMI parameters. This will indicate to the user that something occurred during the data call.

1 SMS-STATUS-REPORTs are routed to the TE using unsolicited result code: +CDS: <length><cr><lf><pdu>

<bfr>: 0 TA buffer of unsolicited result codes defined within this command

is flushed to TE when <mode> 13 is entered (OK response is returned before flushing the codes)

AT Command Set

+CSCB Parameters• The default value for missing <mode> is 0.• A comma must be followed with a value.• When using <dcs> GSM 3.38, only non compressed messages with default

alphabet or UCS2 are transferred to TCU, and 8-bit data support is required.• No more than 16 channels will be submitted in <mids>.• The string type list <mids> and <dcss> may include only numbers (0-9), blanks,

comma and minus (-) characters.• <mids> = 1-5 is equivalent to five channels.• When <mode> is 0 and <mids> is a non-empty list, the list will be added to the

current G18 list. An error will not be issued if an item does not exist in the G18 list.• When <mode> is 1 and <mids> is a non-empty list, the list will be deleted from the

current G18 list. An error will not be issued if an item does not exist in the G18 list.• The <dcss> list can include schemes that are not handled by G18, without error

notification.• AT+CSCB=0, “x,x”, “y,y”

When specifying a mid or a dcs several times in the same AT+CSCB request, the mid/dcs will be added the same number of times to the G18 internal lists.

• AT+CSCB does not affect or represent SIM cell broadcast channel/language lists.• The dcss specified refers to all incoming messages, and not only to mids specified

in the same AT command. For example, AT+CSCB=0, “1-5”, “1-7” followed by AT+CSCB=0, “6-10”, “8” will update the G18 mids list to 1-10, and the dcs list to 1-8. Any CB message that arrives with mid value of 1-10 and a dcs value between 1-8 will be accepted by G18.

Cell Broadcast Support in G18• The G18 allows selection of the SMS service for cell broadcast. The AT command

for selecting the service is:• +CSMS=<service>• +CSMS?• <service> 0 is allowed

• The G18 supports text and binary data coding schemes for cell broadcast messages.

3-117


• The number of concurrent cell broadcast channels from which the G18 forwards cell broadcast messages to the DTE is not less than 21. (Five of the channels are user-defined lists through SIM and menu handling).

• The G18 NAD delivers multiple pages of a cell broadcast messages to the DTE. Each page is sent as an individual message, even though the pages will be delivered in page based sequence.• AT+CNMA in not requested for cell broadcast.• G18 is unable to save all pages being processed in its memory. G18 will send

each page as it arrives. The page could not be a duplicate, or unorganized and multiplexed with other pages. TCU should reconstruct messages and remove duplicates. These messages should be shown to the user only after a successful build.

• The G18 supports up to 15 pages in a message.• the G18 NAD does not store CBM messages in SIM or NRM.• +CNM’s <bm> value is not conververted to 0 by G18, unless requested to do so.

• Messages are sent to the TCU only when CNMI’s <bm> value is 2, and either +CSCB’s channel list is not empty or SIM user’s list is not empty.

• The following two entities may be required to handle or listen to cell broadcasts:• DTE using AT+CSCB command• User predefined SIM list, where the user controls the list using the handset

menu.These entities will be referred to later as requesters.

Incoming Cell Broadcast MessagesIn release up to E6.11.23, the handset is set to receive accumulated messages. This means that if the message exceeds one page then the message is not sent to the handset until whole message is accumulated in a buffer. The maximum number of accumulated pages is three, which means that sometimes only part of the intended message is sent.Using AT+CSCB, DTE is set to receive page-by-page messages, meaning that a message with several pages is reported to DTE page by page.There will be two behavior methods: One that keeps the previous release’s behavior (backward compatible), and another for those who will use AT+CSCB.

• Previous version-SIM/handset is the sole requester (by default, after AT+CSCB=0 or any other sequence of AT commands that leads to an empty G18 CSCB’s mid list):• CB control (on/off) is via Menu-Messages-Cell_Broadcast-On/Off

3-118

AT Command Set

• mid control is via Menu-Cell Broadcast-Channel index• dcs control is via Menu-Messages-Cell Broadcast-Languages• Messages received accumulated.• Maximum number of pages received in a message is three.• Handset does not support 8-bit data and compressed data. Additional

screening by data coding scheme is done via the SIM language list.• AT+CNMI=0,0,2 is required to transfer data to DTE.

• G18 mid list assigned by AT+CSCB is not empty:• DTE gets all messages page by page (maximum of 15 pages per message).

Messages are not sent to handset.• G18 tracks incoming cell broadcast messages. After receiving a CB message

with a specific mid, G18 will not receive CB messages with that same mid unless its update number is different. For example, CB mid=1, update=-CB is acce[pted; CB mis=1, update=1- the CB is not accepted; CB mid=1, update=2- CB is accepted; CB mid=1, update=1-CB is accepted.

AT+MSCTS, Sleep CTS Control

NoteThis new activity AT command controls CTS behavior and will deactivate it when the unit is in sleep mode. When there is no activity, g18 may enter the sleep-awake sequence, which can occur every 30-40 milliseconds.When sending data, use the wakeup line, either pin #15 at the FC 36 pin, or pin #10 at the DIN 28 pin, to awaken the g18.This command is supported in software versions E6.13.24 and above.

WARNING

When the DTE is not connected to the wakeup line, do not use this command.

Using AT+MSCTS=1 will deactivate the CTS after g18 has entered sleep mode, and the DTE will be unable to communicate with the g18 until powered on.
