Virtual Serial Ports： a software package that allows you to create virtual COM ports

Virtual Serial Ports

HHD Software 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 with another virtual COM port in a local bridge with flow control and baud rate emulation.

2. Connected with remote virtual COM port over network with flow control and baud rate emulation.

3.Connected to a named pipe.

4. 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:

Virtual Serial Ports Device Driver 
This device driver implements the functionality of the virtual serial port device. It operates in user mode space, unlike most other device drivers, making the system more stable and secure.

Virtual Com Ports ActiveX Control 
Provides rich application programming interface (API) for applications that want to create and manage virtual serial ports.

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.

Virtual Com Ports Command-line Utility 
Provides command-line interface to create and manage virtual serial ports and bridges.

Usage Areas

Virtual COM Ports can be successfully used to:

• create any number of virtual COM port pairs connected via a virtual null-modem cable
• share virtual COM ports data with files and named pipes
• add unlimited number of COM ports to your Windows operating system
• record COM port application data transfer to a file
• emulate rs232 null modem cable
• develop rs232 peripheral hardware
• research the functionality of third-party software and hardware
• implement, debug and test serial protocol between device and device driver
