TMS Async is a comprehensive set of components designed for implementing asynchronous serial communications in Delphi and C++Builder VCL applications. It provides fast, non-blocking, multi-threaded handling of COM port data transfer along with specialized components for terminal emulation and modem protocol operations. The library is essential for Windows‑based software that must reliably read and write data over serial interfaces.

Features

• Wide range of serial communication components for building robust Windows VCL applications.
• Fast, non‑blocking, multi‑threaded buffering architecture ensuring responsive and stable communication even under heavy I/O load.
• Built‑in support for legacy and widely used modem transfer protocols, including:
  • XModem
  • YModem
  • ZModem
• Terminal display component with an extensible emulation interface for supporting additional terminal types or behaviors.
• Full COM port communication support including configuration, control signals, and event‑driven data handling.
• Optimized for Windows environments where direct serial port manipulation is required.

Benefits

• Reliable Serial Communications: Allows developers to confidently integrate COM port functionality without dealing with low‑level Windows API complexity.
• Improved Application Responsiveness: Multi‑threaded buffering architecture prevents UI freezes and ensures smooth data flow.
• Faster Integration: Pre‑built modem protocol support saves significant development time when implementing file transfer over serial links.
• Customizable Terminal Experience: The extensible terminal component enables tailored emulation scenarios for specialized hardware, diagnostics, or embedded systems.
• Ideal for Industrial & Embedded Use Cases: Perfect for device configuration tools, machine interfacing, embedded system communication, instrumentation dashboards, and legacy hardware integration.
