Introduction 1.2 Using this manual The standard text in this manual is modified to distinguish between the text displayed on the screen, typed instructions and examples of command dialog. The distinctions are as follows: 1) Typed commands and option values are written in bold text. For example: 2) Options: 0 - 127 Any key strokes are written in bold text in brackets.

Introduction 1.3 Using the Ericsson Mobile Office Suite Telephone The telephone connects to your computer via an Infrared Modem by means of a digital infrared link. Data functions Transmission speed conforms to the ITU-T standard V.22bis which facilitates data transfer at 2,400, 4,800 and 9,600 bits/s. By implementing data compression the transmission speed can be increased to a theoretical maximum data throughput of 38,400 bits/s. between computers.
PAGE 8
Introduction 1.4 Communications programs Please refer to the User Manual for instructions on the installation and use of the Ericsson Infrared Modem software drivers. Configuring third party communication programs If you want to use a communication program which does not include the Ericsson Infrared Modem in the list of supported hardware, the following options are suggested: Configure for V.25ter The Infrared Modem supports the V.25ter command set.
PAGE 9
Introduction Configure your facsimile communications program manually To manually configure your facsimile communications program, select a Fax Class 1 driver. The Infrared Modem supports Fax Class 2 facsimile which might be used if there are problems with the fax service or speed of the computer, or your fax application does not support Fax Class 1.
PAGE 10
Result and Error Codes 2 Result and Error Codes 2.1 Result codes When you send a command from your PC to the Infrared Modem, the response is terminated by a result code which is shown on the computer screen. You use this code to confirm correct operation or to identify any problem with the command. There are two types of result codes: • • final result codes related to the operation of AT commands; result codes associated with call connections.
PAGE 11
Result and Error Codes ERROR An error has occurred during the command processing. This could arise because: • there is a fault in the command syntax; • one or more parameters are outside the permitted range; • the command you issued is not implemented on the Infrared Modem; • the command is not appropriate to the service; • class the Infrared Modem is operating. When an error is reported, the ERROR message is preceeded by a copy of the text response from the last valid AT command.
PAGE 12
Result and Error Codes Result codes from call connections During on-line operation of the telephone, result codes inform you about the progress of call connections: CONNECT A connection has been established and the data rate is shown. BUSY The number you called is engaged. NO DIALTONE Unable to establish the initial connection. NO CARRIER Either a connection could not be established or an existing connection has been lost. RING There is an incoming call.
PAGE 13
Result and Error Codes 2.2 Error codes The +CME ERROR result codes indicate an error relating to the functionality of the Infrared Modem or Mobile Phone and replaces the final result code ERROR when first enabled with the AT+CMEE command. Report mobile phone failure (+CMEE) +CME ERROR: 0 Phone failure. +CME ERROR: 1 No connection to phone. +CME ERROR: 2 Phone modem link reserved. +CME ERROR: 3 Operation not permitted. +CME ERROR: 4 Operation not supported. +CME ERROR: 5 PH-SIM card PIN required.

AT Commands 3 AT Commands 3.1 Introduction to AT commands This chapter describes how AT commands are used to exchange information with your mobile telephone and Infrared Modem. The AT commands are listed at the end of this chapter. For a description of each command, refer to Chapters 4, and 5.
PAGE 18
AT Commands 3.3 Changing the Infrared Modem operating mode The following illustration summarises the methods that are used to switch between the three Infrared Modem operating modes: Power up Off-line Command Mode Exchange AT command data between computer and Infrared Modem Lose carrier or lose I.R. link or press “No” button or pull DTR low or ATH Dial Answer ATD ATA On-line Data Mode Exchange data or facsimile Lose carrier or lose I.R.
PAGE 19
AT Commands Operating in off-line command mode In off-line command mode, the Infrared Modem accepts data as commands and not as normal communications traffic. You enter commands by typing at the PC keyboard. Switching to on-line data mode To enter on-line data mode, so that you can exchange data with the modem at the other end of the link, you enter the ATD command followed by the telephone number to make the call.
PAGE 20
AT Commands Using AT commands during a data connection If you wish to use AT commands while connected to a remote modem in online data mode and maintain connection with the remote modem, you must first enter on-line command mode. There are two ways you can switch from on-line data mode to on-line command mode: • Type the escape sequence “+++” followed by an appropriate AT command. This command must be selected from the options AT, ATE, ATH, ATI, ATL, ATM, ATQ, ATV and ATX.
PAGE 21
AT Commands 3.4 Operating the AT commands In command mode, there are four types of command you can issue: • a set command to adjust the Infrared Modem’s operating parameters; • an execute command which directs action without the need of any parameters; • a read command to view the current command settings; • a test command to view the available command parameters. Not all AT commands support all four functions. The descriptions in Chapters 4 to 6 list the functions available for each AT command.
PAGE 22
AT Commands To set the Infrared Modem to operate with autobaud over an asynchronous connection the command line would be: AT+CBST=0,0,1 However, the commands also have default settings. These are values which are assumed to have been entered when no actual value is placed in the command line. For example, the above command can be entered as: AT+CBST=,,1 The default values used by the commands are indicated in the following descriptions by bold text.
PAGE 23
AT Commands To answer an incoming call, you execute the A command: ATA Using read command to view the command settings To check the current settings of a command, use the ‘?’ option.
