Microsoft does not encourage nor support user changes to .INF files; therefore, Microsoft Product Support Services (PSS) does not support the procedure in this article. Although we have tested the following procedure and it appears to function as described; we strongly recommend that you make a backup copy of your .INF file before you proceed.

= SYMPTOMS =

When you use Remote Access Services (RAS) with a US-Robotics Internal 14400 Sportster, you receive the following error messages: Error 692: Hardware Failure in attached port or device

= RESOLUTION =

To correct this problem, edit the modem initialization entry (COMMAND_INIT=) in the [US Robotics Sportster 14400] section of the MODEM.INF file. To do so: 1. Run Microsoft Windows for Workgroups Write and open the MODEM.INF file. 2. Choose the No Conversion button. 3. From the Find menu, choose Find. 4. In the Find What box, type “[US Robotics Sportster 14400]” (without the quotation marks) and then choose Find Next. 5. Choose Cancel and then change “AT&F” to “ATZ&F” (without the quotation marks). For example, change COMMAND_INIT=AT&F&C1&D2 V1 S0=0 S2=128 S7=55 W1 S95=44 to: COMMAND_INIT=ATZ&F&C1&D2 V1 S0=0 S2=128 S7=55 W1 S95=44 6. Save the MODEM.INF file. 7. Quit and restart RAS Phonebook. This issues a reset command first, and then resets the modem to the factory defaults.
