Section 2.6 Install Communication Software

Y ou can install the communication software from the CD-ROM disc attached with your new modem. Please consult the software manual in the CD-ROM disc for the detail of software installation.

Y ou do not have to use the communication software attached with your new modem. The modem was designed for and tested using a wide range of communications software packages. Many communication applications identify the modem automatically and configure themselves for the correct operating settings. Some of the communication applications will ask you to select the type of modem you are using. Select a Generic Fax class 1 modem will let you use

basic communication and fax functions.

Section 3 T roubleshooting

Your modem is designed to provide reliable and trouble-free functionality, however, should you experience any difficulty , the information contained in this section will assist you in determining and resolving the source of the problem.

Problem: Modem does not respond to A T commands Possible solutions:

1. Make sure the modem is not configured with a conflicting COM port and IRQ setting. Make sure the

communication software is configured with the correct COM and IRQ settings (the same COM port and IRQ as the modem). Your communications software will not be able to send or receive any data if it is not configured to match the COM port and IRQ settings for the modem.

E500 V.90 USB MODEM USER'S MANUAL

DOS based communication program is not working with this modem neither can you operate the modem in MS-DOS prompt screen.

2. Make sure the modem is properly initialized using the driver software. The software may improperly initialize your modem because you have selected an incorrect modem type. You may also be prompted to enter an initialization string by the software. Use AT&F as your initialization string.

Problem: Modem dials but does not connect Possible solutions:

1. Be sure the IRQ setting and USB port is identical on the modem and the software.

2. Make sure that the phone line is working properly . A noisy line will prevent proper modem operation.

Problem: Modem makes a connection but no data appears on screen Possible solutions:

3. Make sure all communication parameters (baud rate, data, stop, and parity bits) are properly configured and

are identical on both sides. Be certain hardware flow control (RTS/CTS - default) is enabled in both the modem and the communication software.

4. Press the ENTER key several times. The remote system may be waiting to receive your data before it begins.

5. Make sure the correct terminal emulation mode is being used in the software (refer to software manual).

Problem: Modem displays errors while on-line with a remote modem Possible solutions:

6. Make sure Call Waiting is turned off.

7. Make sure RTS/CTS hardware flow control is enabled (do not use XON/XOFF software flow control when

transferring binary files).

8. Make sure the data speed is not faster than your computer capability . Operating too many applications at the same time may cause communication problem. Close unnecessary application in your System.

Problem: Modem exhibits poor voice recording or playback Possible solutions:

9. Make sure the correct modem type is selected in the Voice/FAX software. Volume adjustment is available in

control panel.

10. Make sure your computer is fast enough to handle voice operations (38.4 Kbps). V oice operations are CPU intensive and require a better CPU sharing when running under Windows.

Problem: No dial tone Possible solutions:

11. Ensure that the telephone cord it securely connected at both modem and wall outlet.

12. Unplug the telephone cord from the computer and connect it directly to a telephone from the wall outlet.

Check for a dial tone. If there is none, the problem is in the telephone cord or system. Call your telephone service provider.

13. Double-check your country setting. Different country setting will cause different modem performance. Please select the correct country as you located.

14. Check modem performance with a direct line from your telephone company. Some PBXs may cause the telephone line condition change and affect modem performance.

E500 V.90 USB MODEM USER'S MANUAL

Problem: The modem does not answer incoming calls Possible solutions:

15. Ensure that the automatic answer parameter is set to one of the enabled options, using the ATS0 command

(A TS0=1 to answer af ter one ring, and so on).

16. Ensure that no other devices, such as fax or answering machines, are answering calls before the modem does.

If you can not resolve your situation after reading this section, contact your dealer or vendor for assistance.

Appendix 2 ModioTM AT Commands Sets

Modem operation is controlled by A T commands. These A T commands include the following:

- Basic AT commands, for example ATDT123

- Extended A T Commands for example A T&E,A T\A,A T%C,AT+MS

- S-Register commands, for example A TS0=1

- Fax Class 1 commands, for example A T+FTM

- Voice commands, for example A T#VTX

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:

E500 V.90 USB MODEM USER'S MANUAL

- Basic AT commands consist of single ASCII characters, which may be preceded by a prefix character, for example &, and followed by a decimal number, for example AT&W1.

- Missing decimal parameters are interpreted as 0. For example, if you type ATH , the command ATH0 is assumed.

- Fax commands are preceded with the +F characters and terminated by semicolon (;) or <CR> character.

- The modem supports editing command lines by recognizing the <BS> character.

- The AT command sequence may be followed by any number of commands in sequence, with the exception of commands Z, D or A, where all characters following on the same command line will beignored.

- When a syntax error is found in the command line, an ERROR response will be returned to the DTE. Execution of commands D and A will be aborted if another character is entered before completion of the hand shake.

- When the modem has entered on-line data mode, it is possible to break the data transmission in order to is sue more AT commands. This is done by the DTE sending a sequence of three escape characters (defined in S2, ‘+’ by default).

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 current version of Modio.

Basic A T 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>.
