Free Virtual Serial Ports

by HHD Software Ltd.

HHD Software Free Virtual Serial Ports is a software package that allows you to create virtual COM ports.

Created virtual COM port may be used in one of the following ways:

  1. Connected to a named pipe.
  2. Connected to another virtual COM port, forming a virtual "bridge" and emulating virtual Null-modem cable.
  3. Connected to two files. When an application opens a virtual COM port and "reads" data from it, data is read from an input file, and when it "writes" data to a serial port, data is written to the output file.

Product Organization

Technically, the product consists of the following components:

Free Virtual Serial Ports Device Driver

Free Virtual Com Ports ActiveX Control
Provides rich application programming interface (API) for applications that want to create and manage virtual serial ports.
Free Virtual Com Ports Configuration Utility
An example of ActiveX Control API client, which provides simple user interface for creation and management of virtual serial devices.
