US Robotics USR5610C 56K V.92 PCI Controller-Based Hardware Fax Modem (Dell P/N KX776 / Model 0778)

Authentic US Robotics USR5610C 56K V.92 internal PCI hardware faxmodem (Product Code: USR5610C-VAR-20 / Model 0778 / PCB USR-1 012 0778-F). OEM version pulled from a Dell Precision / OptiPlex desktop system (Dell Part Number: KX776 / 0KX776).

Unlike common software-driven winmodems, this is a true controller-based hardware modem powered by a dedicated onboard Texas Instruments DSP processor (1.016.1223), TI bus controller (1.016.1777-00), ISSI SRAM, flash memory, and integrated speaker. It processes data on-card with zero host CPU overhead, making it exceptionally reliable and natively compatible across Linux, MS-DOS, FreeBSD, UNIX, Windows 95/98/ME/NT4/2000/XP, and modern 64-bit systems. Highly sought after for industrial dial-up telemetry, legacy server management, and automated POS fax servers.
