7.4.1 Ensuring Proper Configuration of the MODEM

To ensure that the MODEM retains the set configuration, the user should utilize HyperTerminal at

the Host PC. The HyperTerminal program will set the configuration in the MODEM for constant

uninterrupted use with the IQ-400. In the following procedure, the Init String will be written into the

NOVRAM and therefore a power loss to the MODEM ONLY will not result in a continuous loop.

•

Set switches 1, 5, 6, and 7 in the U.S Robotics Sportster MODEM (14.4K, 28.8, 33.6, or

56K) to Up. All other switches should be Down.

•

Connect the MODEM to the PC using a standard PC to MODEM cable.

•

From the PC (Win95/98/NT) access HyperTerminal by entering the following commands:

1. Click on Start: Programs: Accessories, and then, HyperTerminal. The

Connection Description dialog box will now appear.

2. Type in a name for the connection (for example: MODEM TEST). Click on a

corresponding icon from the list. Click on the OK button.

3. The Connect To dialog box will now appear. The proper communications port used

to communicate to the external MODEM is now selected within the Connect Using

field (for example: COM2). Click on the OK button.

4. The COM# Properties dialog box will now appear. Select 9600 in the bits per

second field. Select 8 in the Data Bits field, None in the Parity field, 1 in the Stop

Bits field, and Hardware in the Flow control field. Click on the OK button. The

screen will now clear and the cursor will be at the top left corner of the

HyperTerminal window. Type ATV1 E1 and press Enter. The MODEM will respond

with OK.

5. Type ATI3 and press Enter to display the type of MODEM connected, followed by

OK.

6. Type ATI4 and press Enter to display the MODEM’s current settings, followed by

OK.

7. Type ATI5 and press Enter to display the MODEM’s NVRAM settings, including any

stored telephone numbers, followed by OK.

8. Type ATEVQHSØ=1X&DØ and press Enter. The MODEM will respond by

changing the A in the previous String to a Ø (zero).

9. Type AT&WØYØ and press Enter. No visual indication will be displayed as the

MODEM was configured in the previous step to use Numeric Result Codes.

10. Type ATZ and press Enter. As in the previous step, no visual indication will be

displayed.

11. Click on File, then Save, to save the configuration file.

12. Click on File, Exit, then Yes, to disconnect from the MODEM and exit

HyperTerminal.

13. Power down the MODEM and turn switch 1, 5, and 6 up. All others should be

down. Connect the MODEM to the IQ-400. Perform functional testing.
