USB Modem
Introduction
The goal of this manual is to provide general information for the developers on evaluation of the USB Modem. The USB provide a 12Mbps high bandwidth for virtually unlimited data throughput instead of the legacy 16550 UART bottleneck with the traditional modems.
USB Modem is a very flexible modem that has one of the smallest real estate and power consumption out on the market. Because of the simplicity of the modem design, the time to market is quick and less overhead. With this modem, all future driver releases will be a simple software update.
USB modem provides an easy installation and a strong performance that reduces the Total Cost of Ownership.

AT* Commands - Black List Support
Start your PC as usual, then plug in USB Modem to any spare USB port on your system. Windows will report that it has found a new hardware and will open the Add New Hardware Wizard reporting that it searches for the new drivers for an Unknown Device.
Click on the Next button.
Windows will propose to search for the best drivers for your device.
Click on the Next button. Insert USB Modem software CD-ROM or USB Modem driver diskette.
Select CD-ROM drive or Floppy disk drive in the Add New Hardware Wizard window and click the Next button. If installing from CD-ROM, specify the drivers directory when
The driver for USB Modem will be proposed.
Click on the Next button. Windows will build a database for this device.
Click again on the Next button to finish the installation of the USB driver.
Windows will then detect again a New Hardware and will install the Modem drivers.
At the end of this installation process, the Device Manager panel of the System Properties will show the addition of USB Modem in the Modem section and the driver for USB Modem in the USB section:
Finally, double click on the USB Modem and choose the modem folder as shown below.
In the Configuration section you can choose the country that you are calling from. This way you can take the USB modem and be able to dial from any country worldwide.
Modem operation is controlled by AT commands. These AT commands include the following:
The command syntax and operation guidelines for each command category are described in the following sections.
A command line is a string of characters sent from a DTE (Terminal or Data Terminal Equipment) to the DCE while the DCE is in command state. Command lines have a prefix, a body and a terminator. The prefix consists of the ASCII characters AT or at. The body consists of printable ASCII characters. Space characters other than <CR> (See register S3), and <BS> (See register S5) are ignored. <CR> is command terminator.
Characters preceding the AT prefix are ignored.
AT Command Guidelines
The modem will comply with the commands listed below. Parameters applicable to each command are listed below.
Default factory configuration settings are marked by an asterisk *.
Features marked with (-) are not yet available in the current version.
Basic AT Commands
| A/ | Re-execute
Command The modem repeats the last command line sent by the DTE. Usually used for re-dialing. Note: This command should not be terminated by <CR>.
|
| A | Answer The modem will go off-hook and attempt to answer an incoming call. Upon successful completion of handshake, the modem will go on-line in answer mode. Notes: If +FCLASS=0 is selected, the modem will enter the connect state after exchanging carrier with the remote system. If no carrier is detected within the period specified in S7, the modem hangs up. Any character entered while connecting will abort the connection process. If +FCLASS=1, the modem will go off-hook in V21 answer mode. It will generate the V21 2100 Hz answer tone for 3 +/- 0.5 seconds, and following a delay of 70 ms, will proceed as if the +FTH=3 command were issued. At any stage up to (but excluding) the +FTH=3 command state, any character will abort the communication. If +FCLASS=8 (#CLS=8), the modem will go off-hook and a voice session will take place.

| Bn | CCITT Control B0 Connect at V.22 1200 bps
Result codes: OK n=0 Error Otherwise
|
| Dn | Dial Directs the modem to go on-line, dial according to the string entered, and attempt to establish a connection. The Dial String may consist of any of the characters described below: |
| * | T Tone dialing (first character in the string) P Pulse dialing (first character in the string) L Redial last dialed number (first character in the string) 0-9 Digits 0 to 9. * Asterisk (tone only) # Hash (tone only) W Wait for dial tone; the modem will wait for dial tone before dialing the digits following “W”. S6 register will be used for timeout. (X3 or higher) , (Comma); Pause for the time specified by S8 before resuming the dialing ; (Semicolon) Return to command mode after dialing. This allows the user to issue additional AT commands while remaining off-hook. Actual call progress will be entered only after a dial command issued without the “;” terminator. S=n Dial the number stored in the directory; n=0-3 (see &Z). ! Flash; The modem will go on hook for a time defined by S24. @ Wait for silence; The modem will wait for at least 5 seconds of silence before resuming the dialing. If no such silence is detected before the expiration of the call abort timer (S7), the modem will terminate with NO ANSWER response (or BUSY if applicable). If answer tone arrives during execution of this parameter, the modem handshakes. (X3 or higher) (),< > (space) String format characters - ignored <i> any other character - ignored. Notes: If +FCLASS=0 is selected, the modem will attempt to connect with another data modem. The modem will use the time period specified in S6 and S7 as time-outs in the handshake process. If a timeout expires, the modem will go on-hook and respond with NO CARRIER response. The command will be aborted in progress is a DTE character is entered before completion of the handshake. If +FCLASS=1, the modem will attempt to connect with a fax machine (or modem) by entering the HDLC V21 channel 2 receive state (as if +FRH=3 had been issued). The command will be aborted upon receipt of a DTE character if the modem has not finished dialing. In this case the modem will go on-hook and return to command mode responding with NO CARRIER message. If the modem has finished dialing, It proceeds as if +FRH=3 command has been issued. If +FCLASS=8 (#CLS=8), the modem will go off-hook in V21 answer mode. It will decide (based on timers) when the other side answers in voice and a voice session will take place.

| +MS | Modulation select This command selects the modulation, optionally enables/disables Automode, and optionally specifies the lowest and highest connection rates. The command format is: AT+MS= [<mod>][,[<automode>][,[<min_rate>][,[<max_rate>]]]] <mod> a decimal number specifying the preferred modulation (automode enabled), or the modulation (automode disabled). <automode> 0/1 Automode disabled/enabled <min_rate> minimum rate for connection. If lower than the actual minimum rate for the selected modulation, the actual lowest supported rate will be taken. <max_rate> maximum rate for connection. If higher than the actual maximum rate for the selected modulation, the actual highest supported rate will be taken.

AT* Commands - Black List Support
Note: The following command will always return OK as a result code.
| *B | Return
Blacklisted numbers
Blacklisting is a country dependent parameter.
When no time-out is defined: When a number is unsuccessfully called x successive times, it is blocked altogether, until next system reset. Further calls will return BLACKLISTED code.
When time-out is defined: When a number is unsuccessfully called x successive times, it is blocked temporarily until the time-out expires. Calls within the time-out period will return DELAYED code.
Format:
No. Called Blocked Phone Index # of calls ' ' (blank) Phone number - not blocked (number still candidate for blacklist) or '*' (asterisk) - blacklisted/blocked or 'Xmin' - # of min to time-out - delayed
Example 1: No time-out defined. Full blocking occurs No. Called Blocked Phone 1 5 * t1234 2 3 t5678
Example 2: Time-out defined. Delay scheme used. No. Called Blocked Phone 1 5 2min t1234 2 3 t5678 |

The S-Registers are summarized in the following table. Registers denoted with a * may be customized using the PTT Wizard Tool.
Factory defaults
Factory defaults are stored in the Windows OS registry. They are loaded at initialization time or by AT commands (&F,Z). In addition the designated default profile (as specified by the Yn command) is subsequently loaded.
The defaults shown are of the Smart Link factory settings 0 and 1.
S-Register Summary
Note: This S-register List is not to be used as is by End Users and in End User’s manuals.
For end users the contents of the first 24 S-registers should suffice.
