Conexant 56K Data Fax Voice Modem (RCV56ACF) Driver

The Conexant 56K Data Fax Voice Modem (RCV56ACF) driver helps Windows recognize the modem and communicate with it for dial-up data, fax, and supported voice functions. It is intended for users setting up legacy telephone-line hardware, restoring a missing modem entry, or troubleshooting a device after reinstalling Windows.

Listed under Microsoft as the driver vendor and Network as the category, this device has driver support listed for Windows 10, 8.1, 7, Vista, and XP. Match the download to your Windows version and system architecture before installation. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the listed supported systems.

Key Features

• Modem recognition: Allows Windows and compatible applications to identify and access the RCV56ACF modem.
• Dial-up connectivity: Supports data communication over a compatible analog telephone line, with actual connection speeds dependent on line quality and service conditions.
• Fax functionality: Provides the driver interface needed by compatible fax software to send and receive documents.
• Voice-capable operation: Enables access to supported voice features when used with suitable modem hardware and software.

How to Install Conexant 56K Data Fax Voice Modem (RCV56ACF) Driver

1. Check your system and device. Confirm your Windows edition and whether it uses a 32-bit or 64-bit architecture. In Device Manager, check the modem name or hardware IDs to verify the device match.
2. Choose a compatible package. Before starting the Conexant 56K Data Fax Voice Modem (RCV56ACF) driver download for Windows, review the package’s supported operating systems. A free download still needs to match your hardware and Windows installation.
3. Prepare the files. Extract the archive if necessary. If replacing a working driver, consider creating a restore point before making changes.
4. Install the driver. Run the supplied installer, if available. Otherwise, open Device Manager, right-click the modem or unidentified device, select Update driver, and browse to the extracted driver folder.
5. Verify operation. Restart if prompted, check Device Manager for warnings, and test the modem using compatible dial-up or fax software and an analog telephone connection.

Keep the driver updated when a compatible release addresses a problem you are experiencing. Choose the latest version that explicitly supports your modem and operating system; a newer package is not automatically the right update for legacy hardware.
