ATI Commands

You can sometimes learn useful information about your modem by talking directly to it.  The ATI commands (AT = attention I = information) are standard throughout the modem industry and will return some information on nearly every functional modem

What Operating System are you using?

• Windows 3.1
• Windows 95/95/ME
• Windows 2000

The Procedure for Windows 3.1

1. From the Program Manager, click on the File menu, then choose Run.
2. Type terminal.exe, then click the OK button.
3. Make sure that the correct COM port is selected under Settings and Connector. Click the OK button.
4. At the blinking cursor, type: ati1, then press enter. Write down the information reported.
5. Repeat this step for ati2, ati3, and so on, all the way through ati7.

Although we don't all speak "modem" and won't necessarily be able to interpret all the information reported, look for any legible words. ATI3 or ATI4 usually report brand names in newer modems. You should also be able to find your modem speed. One or more commands should say 14400 or 28800 or higher, buried within the other text strings. If you see no speed, or if you get "ERROR" as the response on everything higher than ATI4, you may have an older 2400/9600 baud modem that will not work properly with our modem banks.

Look out for the phrases "Rockwell RPI" or "Winmodem." These modems require special software to function properly, and will often not function at all with some dialer programs.

If all you can discern is the compnay name, you can contact that modem manufacturer with the rest of the information and then they can determine the best settings.

2. Double-Click Control Panel.
