Control Windows Mobile 6.5 from PC with VNC

During the era of Windows Mobile 6.5, controlling a handheld device from a desktop computer was essential for enterprise deployments, application developers, and everyday power users. While modern smartphones rely on protocols like Miracast or specialized cloud-based MDM platforms, Windows Mobile relied on native VNC servers and dedicated ActiveSync utilities to mirror displays and capture desktop mouse and keyboard inputs over USB, Wi-Fi, or cellular networks.

Native VNC Solutions: PocketVNC and MobileVNC

Users looking for true VNC interoperability relied on dedicated VNC server ports compiled for the Windows CE and Windows Mobile architecture.

  • PocketVNC / EfonVNC: One of the earliest open-source VNC servers adapted for Windows CE and Windows Mobile. Once the server executable was running on the device, any standard desktop VNC viewer—such as UltraVNC, TightVNC, or RealVNC—could connect over the local network via IP address.
  • MobileVNC: Specifically optimized for Windows Mobile 5.x, 6.x, and Windows CE, MobileVNC offered improved performance by hooking directly into the display driver pipeline. This reduced latency and allowed smooth cursor interaction and keyboard mapping from the PC.

Microsoft Remote Display Control

Developed directly by Microsoft as part of the Windows Mobile Power Toys, Microsoft Remote Display Control was the standard free utility for developers.

Unlike conventional VNC servers that relied strictly on TCP/IP networking, Remote Display Control utilized the Remote API (RAPI) built into Microsoft ActiveSync (and later Windows Mobile Device Center on Windows Vista and 7). Because it communicated directly over the ActiveSync USB tunnel, users did not need to configure network routing, IP addresses, or firewalls on the handheld unit.

My Mobiler

My Mobiler became the most widely adopted third-party tool for controlling Windows Mobile 6.5 screens. While it operated similarly to VNC, it was specifically designed for ease of use alongside ActiveSync.

  • Features: Full keyboard and mouse passthrough, real-time screen capture, clipboard synchronization, and integrated file browsing.
  • Connectivity: Automatically initiated a display session upon detecting an ActiveSync or Windows Mobile Device Center connection over USB or Bluetooth, though it also supported direct IP connections over Wi-Fi.

SOTI Pocket Controller-Pro

For corporate and industrial environments using rugged Windows Mobile 6.5 hardware (such as Motorola, Intermec, or Symbol barcode scanners), SOTI Pocket Controller-Pro was the primary commercial standard.

  • Performance: Used proprietary screen compression algorithms that outperformed standard VNC protocols over low-bandwidth or serial connections.
  • Enterprise Features: Included remote task management, device configuration, registry editing, automated macro recording, and integrated video capture tools aimed at IT help desks and technical support staff.
