Testing your modem with the ECHO command
Applicable to: World-Wide
Even though many communication programs offer a command line for testing purposes, this test may be used prior to installing your communication program to verify your modem's functionality and to make sure it is hooked to the COM port you selected in earlier steps. Perform the following steps at a DOS command prompt. Type only the commands shown within the", do not include the quotation marks with the commands. These commands work with most modems, check your modem's manual to verify if your modem supports these commands.
1. Type: "ECHO AT&F>COMX", then hit the ENTER key (X is the COM port number of the serial port the external modem is connected to (or internal modem is set for)). This command sets the modem to factory defaults. Your cursor should return to a DOS command prompt. If an error message such as "write fault error" appears, you may have a resource conflict or your modem may be defective.
2. Type: "ECHO ATA>COMX", then hit the ENTER key. This command instructs the modem to answer the telephone line. The modem should respond with tones as it attempts to "shake hands" with another modem. This will work even if the modem is not hooked to a phone line. If the modem does not respond with these tones, the modem may be defective.
3. Type: "ECHO ATH>COMX", then hit the ENTER key. This tells the modem to hang up and will stop the modem noise.
4. With the modem connected to the line, type: "ECHO ATDT1915170001>COMX", then hit the ENTER key. You should hear the modem dialing. If you dialed a second phone line in your office or home, you should hear it ring.
5. Type: "ECHO ATH>COMX", then hit the ENTER key. This tells the modem to hang up and will stop the modem noise again.
If the modem worked for these tests it is probably good and configured so that it will work with your communication program. Other utilities useful in checking system resources include MSD.EXE which is included with MS DOS and Windows, the "RWVIEW /irq" command in OS/2 which reports IRQ information. There are other programs and utilities that can assist the user in verifying COM port settings include QAPlus/Win which may have been included with your IBM Personal Computer, QAPlus/PRO as well as a variety of other products available in the marketplace. Contact your dealer for more information.
