CONTENTS INCLUDED IN THIS PACKAGE
This chapter describes how to install your Ethernet + Fax/Modem multifunction PC Card. Installation procedures also cover many popular Network Operating Systems.
SETUP : For Windows 95/98 & Windows NT System
The Ethernet + Fax/Modem PC Card in Windows 95/98 has Hot Swap function.
This chapter covers the basic commands and techniques involved in modem operation. In many cases, this is the only information you will need in order to get your Ethernet + Fax/Modem PC Card up and running with communication software, and to start making connections with your PC Card.
The Ethernet + Fax/Modem PC Card communicates asynchronously with computers using AT commands. AT commands are used to configure and control the PC Card. Commands are usually sent to the modem in way of communication software, but can also be entered manually with the computer keyboard.
Command statements must be written in a specific form in order for the Ethernet + Fax/Modem PC Card to recognize them. A command statement always begins with the letters AT or at. It is then followed by one or more commands and the <Enter> key.
AT commands can only be issued when the Ethernet + Fax/Modem PC Card is in "command mode" or "off-line." Once the PC Card has established a connection with another modem, it is said to be "on-line" or in "data mode." In this mode, the characters sent to the Ethenet + Fax/Modem PC Card by your computer are transmitted to the remote modem rather than being interpreted by the PC Card as commands.
Using the Windows 95 Hyper Terminal Program
To issue an AT command statement, you first need to run a communication program such as the Microsoft Windows "Hyper Terminal" program. This program provides a simple method to manually enter AT commands so you can do such things as "customize" the settings of your Ethernet + Fax/Modem PC Card, or store phone numbers you commonly connect to.
Once the Ethernet + Fax/Modem PC Card is connected to your computer’s serial port and telephone line, open the "Windows 95 Accessories" program group, and open the Hyper Terminal Program. The program will prompt you for a name and icon to use for your new connection. Type the name Test Connection then press <Enter>.
Next, you will be prompted for country information, area code, phone number, and the device used to make the connection. For initial test purposes, do not enter a phone number; simply choose the COM port your Ethernet + Fax/Modem is connected to from the "Connect Using" list. Click "OK" when finished.
The next window sets the COM port settings. The settings used for the Comet should be as follows:
Bits per second: |
115200 |
Data bits: |
8 |
Parity: |
None |
Stop bits: |
1 |
Flow Control: |
Hardware |
Click "OK" when finished. After you have done this save your new connection by selecting "Save" from the "File" menu then click "OK." A new connection by selecting "Save" from the "File" menu then click "OK" A new connection icon will be added to your Hyper Terminal folder.
You are now ready to start entering AT commands.
In the terminal window, type:
AT<Enter>
LANmodem responds
OK
This confirms that the modem and your computer are communicating correctly.
To test the telephone line connection, issue the manual answer command. Type: ATA<Enter>
The LANmodem will pick up the phone line, and try to communicate. Normally, this command is only used to answer an incoming call made from another modem, hence the high pitched noise you will hear from the speaker. To abort the operation, press any key, or select "Disconnect" from the "Call" menu.
Dialing and Answering Techniques
Depending on what communications software you use to make modem connections, you may not have much control over how the modem dials the telephone number. This section shows some useful examples of the AT commands used for dialing and answering operations. The command characters specific to each function are shown in bold type.

Chapter 4. QUESTIONS AND ANSWERS
This chapter provides a number of examples of Questions (Q), Causes (C;),and Answers (A:). If your modem is not functioning properly, look up the problem here, or ask your dealer for technical assistance.
Q:The modem does not respond to AT commands.
C:The COMx: port that the modem is set to may be being used by another card in the computer already.
A: Change the COMx: port of the PC CARD FAX/MODEM modem to a different unused port. It might be best to set it to COM3: or COM4 :. Even if you are not using a serial port which is set to the same COMx: port as the modem, it can still interfere with the modem. Be sure to update your software COMx: port setting as well.
C: The Interrupt that the modem is using may be the same Interrupt that another card is using.
A: Change the IRQ settings to a different, unused, IRQ. Even if you are not using a serial port which is set to the same IRQ as the modem, it can still interfere with the modem.
Q: The modem does not execute the command line.
C: Make sure you are typing ‘AT’ at the beginning of command line.
C: Make sure the modem is not in Data Mode. type +++ if necessary.
C: Make sure your software is set to the same COMx: port as the modem.
Q: The modem does not give a response after an AT command was executed.
C: The echo and /or responses may be turned off by the ATEQ1 commands. Use AT&V to check that.
A: Use ATE1Q0 then Enter to change them back.
C: Make sure the modem is in Command Mode and not in Data Mode when you type the AT command.
Q: The modem gives an ‘ERROR’ response after an AT command was executed.
C: The modem may be set to auto-answer the phone when it rings.
A: Disable auto-answer by typing ATS0=0 then Enter at the command line.
Q: The modem dose not auto-answer the phone.
C: If necessary, make sure the software is configured to auto-answer the phone.
A: To set auto-answer mode on from the AT commands, type ATS0=n then press Enter. The n stands for which number of rings the modem will answer on.
Ex: ATS0=3 take the modem answer on the third ring.
Q: The software does not control the modem properly or can not detect the modem.
A: Make sure the software has been set up correctly. Check the initialization and dial strings.
C: Some TSRs (programs that stay in memory after they are loaded) may conflict with the communications software.
A: Try starting your computer without loading any TSRs.
Q: The characters on the screen are doubled.
C: Both the modem and the software have the echo feature turned on.
A: Since only on needs an echo, turn the software echo feature off.
The remote modem is echoing your typed characters.
A: Type ATEI then Enter at the command line, Then turn off the software echo feature.
Q: No text appears on the screen when in data mode.
C: The remote modem is not echoing your typed characters.
A: Type ATE0 then press Enter at the command line. Then turn the software echo feature on.
C: Your software may not be set to use Full Duplex or the remote modem may not be set to use Full Duplex either.
C: The remote modem may be waiting for you to type a command before it will reply with text.
Q: No text appears on the screen when in command mode.
A: If you can’t see the characters you are typing, then type ATE1 then press Enter.
Q: The modem does not dial a phone number after you execute the AT dial command.
C: If you are using touch tone dialing on a phone line that requires pulses, then it may not work. Use ATDT in place of ATDP.
Q: When your communications software tells the modem to dial, it does not.
C: Make sure the software dialing prefix is ATDT.
C: Make sure the software and modem are set to the same COMx: port.
C: The modem may not have hung up the phone line since the last call.
A: Change to command mode and type ATH then press Enter.
Q: The modem can connect to some modems, but not others.
C: The remote modem may not support data compression or error correction, which might cause it to take too long to negotiate a link.
A: You might try changing the way the modem negotiates by using the AT&On, ATNn, and ATS37=n commands. It might be best to start with AT&Q0N1.
Q: When dialing another modem, you receive a ‘CONNECT’ response, but nothing else.
C: The remote modem may be waiting for you to type a command. Or try to press Enter for logging onto the remote site.
Q: The modem disconnects (loses the connection) in the mid-use.
C: The remote modem may have locked up.
C: The telephone switch may have disconnected your call.
C: Your software may have turned off the DTR signal.
Q: The modem does not connect with another modem.
C: There may be a problem with the remote modem if you do not hear the high pitched tone from the remote modem.
Q: Occasionally, the modem gives a burst of errors.
C: The telephone line may be noisy or bad.
A: Hang up the call and try to connect again for getting a better telephone line.
C: If there are other telephones on the same line that your modem is using, someone may have picked up a telephone on that extension.
Q: The modem gets errors in transmitted data randomly.
A: Try to use V.42 or MNP1-4 if possible.
A: Connect the modems at a slower baud rate.
Q: After you download a file, it was not stored on your disk drive.
C: If both modems are using MNP or V.42 protocol, then the flow control may not be enabled.
A: Configure your software to use RTS/CTS flow control. That will cause your computer to pause long enough for the file to be stored to disk.
Q: The text on the screen is not legible.
C: Your software settings may not match the settings on the remote site.
A: Make sure your data bits, stop bits, and parity settings match the settings that the other computer is using. The two most common settings are: 8 data bits, None parity, and 1 stop bit (8,N,1) or 7 data bits, Even parity, and 1 stop bit (7,E,1).
C: If the telephone line is very noisy, you may see corrupted data on your screen.
C: Due to poor telephone line conditions, the modem may have fallen back to a slower communication speed. You may need to change the baud rate setting in your software to match this slower speed. To return the modem to the higher speed, disconnect the link and re-establish again.
Q: When using V.42bis or MNP5, some features are disabled.
C: You may be using a non-streaming protocol, like Xmodem or Ymodem to transfer files. Those are fine unless you are using V.42bis or MNP5.
A: When using V.42bis or MNP5, you should use a streaming transfer protocol like Ymodem-G or Zmodem.
A: Configure your software to use hardware flow control (RTS/CTS ON).
Q: When the modem is connecting to another modem, it reports a higher connect baud rate than it is really using.
C: The modem defaults to report the modem-to-computer baud rate when it responds with CONNECT.
A: Go to command mode with your communication program (like Telix) and type ATW2, then press Enter. This tells the modem to report the modem-to-modem baud rate instead.

The Fax/Modem provides direct access to the internal registers known as S-registers, The DTE uses S-registers to set up and check modem configurations. The contents of these registers can be changed using the ATSn=x command, where ‘n’ is the register number and ‘x’ is the value to be stored. The contents of the S-registers can be read using the ATSn? Command. Most S-registers can be read from or written to; however, some S-registers (such as S14)are read -only. Writing to a read-only register may cause the modem to act improperly (that is, even though the contents of a read-only S-register may be changed using the ATSn=x command, changing the contents of the S-register does not normally configure the entire modem).
Reserved S-registers are used by the modem and provide no valuable information to the DTE. These registers should never be written to, as they cause the modem to lock up. A list of the supported S-registers follows.
