User's Manual 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.
User's Manual 4. Click on the Next button. Insert USB Modem software CD-ROM or USB Modem driver diskette. 5. 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 6. The driver for USB Modem will be proposed. 7. Click on the Next button. Windows will build a database for this device. 8. Click again on the Next button to finish the installation of the USB driver. 9.
User's Manual AT Commands Modem operation is controlled by AT commands. These AT commands include the following: • Basic AT commands, for example ATDT123 • Extended AT Commands for example AT&E,AT\A,AT%C,AT+MS • S-Register commands, for example ATS32=8 • Fax Class 1 commands, for example AT+FTM • Voice commands, for example AT#VTX The command syntax and operation guidelines for each command category are described in the following sections.
User's Manual 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.
User's Manual 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.
User's Manual Ln * Mn * Nn * I5 Stored profile 0 Active Profile 0: (Same format as above) I6 Stored profile 1 Active Profile 1: (Same format as above) I7 Display stored pone numbers (See &Z command) Speaker volume Select speaker volume. L0 Low L1 Low L2 Medium L3 High Result codes: OK n=0-3 Error Otherwise Related S-Reg: S30 Speaker control Select when the speaker is On/Off.
User's Manual On Returns to on-line data mode This command is normally used to connect the DTE back after an escape (+++) has been issued. O0 Return to on-line data mode. O1 Return to on-line data mode, retrain first. Result codes: OK n=0-1 Error Otherwise P Pulse dialing Forces pulse dialing. Applies to subsequent dialing commands. This command holds until the next T dial modifier or T command is received. The modem will go off hook and attempt to answer an incoming call.
User's Manual Xn * Extended result codes Select the subset of result codes to be used by the modem to the DTE. If the modem is in fax mode (+FCLASS=1), the only message sent to indicate connection is “CONNECT” without a speed indication. X0 Supported messages: OK, CONNECT, RING, NO CARRIER and ERROR, Blind call enabled. X1 Supported messages: OK, CONNECT xxxx, RING, NO CARRIER and ERROR, Blind call enabled.

User's Manual five(5.0). To be certain of the number of devices you may connect to your line, as determined by the REN, you should contact your local telephone company to determine the maximum REN for your calling area. If your equipment causes harm to the telephone network, the telephone company may discontinue your service temporarily. If possible, they will notify you in advance. But if advance notice is not practical, you will be notified as soon as possible.
