2400 BPS Pocket FaxModem (250-3105) Setup Faxback Doc. # 5762 Setting Up Your Modem Communications Software Install your modem communications software according to the instructions that came with the program. Some programs do not come with printed manuals, but contain the manual on disk. The first time you use your communication software, you will probably need to tell the software which serial port the faxmodem is using (typically "COM1" or "COM2"). You may also be asked to select the "modem type" from a menu. If you don't see this faxmodem listed by name on the menu, select "Hayes Smartmodem 2400B", or another Hayes-compatible 2400 baud modem. If your software suggests or automatically provides an initialization string for this mode, you should use it. This string of commands will be sent to the faxmodem each time you start the communications program, assuming the faxmodem is already turned on. If this faxmodem (or a similar Hayes modem, as noted above) is not listed by your software and no initialization string is suggested, use the following initialization string: AT &F &C1 &D2 (for PC Compatibles) AT &F (for Macintosh) Note, however, that if you have saved any settings in the faxmodem's non- volatile memory (described in a later section of this manual), the contents of the initialization string will override what you have stored there. In particular, the &F command resets the faxmodem to factory default values. Therefore, if you have saved non-default settings in non -volatile memory, remove the &F from the initialization string. If the software does not provide a dial string, use ATDT. If you telephone service includes "Call Waiting" and you can turn it off by dialing *70 before the telephone number, use the following dial string instead of the one above: Dial String: ATDT*70, (note: be sure to enter the ,) If your software asked you to specify the type of modem you are using, there is probably nothing more you need to do to configure it further. However, if you did not specify the type of modem, you can check the following settings (which should resemble this list): Dialing command suffix: or ^M or ! [Note: this differs from one program to another] Hangup command: ~~~+++~~~ATH0 [Note: ~ means pause. Use the pause character required by your program.] Auto-answer command: ~~~+++~~~ATS0=1 [See previous note.] Wait for connection: 45 (seconds) Pause between redial 1 (second) Auto-baud detect: ON Drop DTR to hang up: YES Send init if CD high? YES Hardware (RTS/CTS) flow control? NO NOTE: The last item in the list above is particularly important. Your software may have taken care of it , but if this faxmodem is not specifically listed, you may have to change this setting to "NO". If this setting says "YES", the faxmodem may work for a while and then appear to "hang" your computer, with the faxmodem totally unresponsive. Setting Up Your Fax Software If fax software came with your faxmodem, it is pre-configured, but you will still need to tell it which serial port you are using. The setup menu will ask you to make some other decisions, for example, the number of rings before answering and decisions relating to the formatting of the page. These are covered in more detail in your fax software manual. Using your FaxModem After you set up your communications software and fax software, you are ready to start using your faxmodem. While you may want to read further in the manual at this point to learn about the AT command set, your best bet is to get familiar with the software that you are using to control the faxmodem, and then to learn by doing. Get started! Try calling a bulletin board, calling a friend with a modem and transferring a file, and sending some faxes. Using the Modem with a Terminal If you're using the faxmodem with a terminal, you can configure most communications parameters using DIP switch settings on the terminal. See your terminal's instruction manual to determine the exact settings required. The fax capability of your faxmodem will not work with a terminal. To change other settings (or if your terminal cannot be configured using DIP switches) you can give AT commands from the keyboard of the terminal and you can store certain configuration information in the faxmodem's non -volatile memory. Using the FaxModem with a Printer or Other Serial Device If you want to use the faxmodem with a printer or other serial device that does not have a keyboard, you'll need a computer or terminal that does have a keyboard to do the configuration. Plug the faxmodem into the serial port of the computer or terminal and plug in the power cube. You may then configure the faxmodem by typing in the appropriate commands from the keyboard. Once you have done the configuration, you can disconnect the faxmodem from the computer or terminal. If you unplug the power cube or turn the faxmodem off, you will lose any configuration parameters that you have not stored in non-volatile memory. The Status Lights There are four status lights on the front of the faxmodem. These lights let you follow the operation of the faxmodem as it sends or receives data. The function of each light is briefly described below. MR (Faxmodem Ready) Faxmodem is receiving power. When the faxmodem is in self-test mode, it will flash. This light dims when the faxmodem is in its low-power state. SD (Send Data) Data or commands are being sent from the serial port of your computer or other device to the faxmodem. RD (Receive Data) Data is being transferred from the faxmodem to your computer or other serial device. LB (Low Battery) Battery power is low. (smc-12/28/93)
