USING THE MODEM
Hints for Good | Use the following information when you set up your communications software to |
Connections | help your modem connect at the highest possible speed: |
| ■ If you have call waiting, disable it. Call waiting generates a tone on the line |
| that causes results similar to static. It also causes your modem to disconnect or |
| report NO CARRIER if a call waiting signal comes when your modem is |
| connected to another modem. Call waiting is usually disabled by using *70 in |
| your dial string before the phone number, for example: |
| ATDT*70 151217288528 |
| Contact your phone company if you need more information. |
| ■ Telephone lines with static or noise slow down transmission and require error |
| correction. If your phone line has a problem with noise, contact your telephone |
| company to see if they can fix the problem. |
| ■ Don’t use a splitter on your telephone line. A single connection from wall to |
| modem produces the highest transfer speed. |
| ■ If the modems do not connect during the handshake, try disabling error |
| correction (use the AT command AT/N0). You can also try disabling data |
| compression (AT/C0). |
|
|
Software Settings | Communications software setup requires information about the modem to make |
| a call or send a fax using the modem. Enter the following settings with the |
| modem software you are using: |
| ■ Select the highest transmission speed or baud rate listed, up to 115,200 bps |
| ■ Select fax Class 1 |
| ■ Select NONE for parity |
| ■ Select a word length of 8 |
| ■ Set the stop bits to 1 |
| ■ Select either |
|
|
Setup for | Virtually all data or fax communications software packages will work if set up |
Communications | correctly for your modem. Read and follow the software installation and setup |
Applications | instructions supplied with your communications application. |
| If the LAN+Modem card is listed in your communications software, the correct |
| initialization strings will be used. If the correct modem does not appear on the list, |
| use the generic 28.8 or 33.6 modem setting. |
