Serial Port Capture Programdownload Free Software Programs Online

This page contains links and downloads for utilities that can be used to decode the data streams of various trunked systems. Many, though not all, of these applications require audio from the Discriminator output of your scanner. Some of the older utilities (like Trunker) require you to convert the audio from your scanner into serial data by using one of the circuits (or pre made units) shown on the Data Slicers page. Newer applications such as UniTrunker, DSD and DSDPlus don't require the use of a data slicer. See the applications' page for more information.


Some of these utilities may also be directly addressed by Software Defined Radios, such as the RTL-SDR, or may be used via piping. For this unit, and possibly many others, see the Big List of RTL-SDR Supported Software.

If you have questions about these utilities, please post on the Voice Control Channel Decoding Software forum. SDR related questions should be posted in the Software Defined Radio forum.

Capturing serial port data. This Win7 machine comes with 9pin serial port and the RS232 cable is ready. Before Win7, this machine was working with XPPro and had a telephony cost accounting called Avaya teletax. With the new Windows, there is no more Avaya software. The only data needed is what the RS-232C serial port.give (number for call.

Share Serial Ports is an advanced utility, the purpose of which is to share real serial ports between multiple applications in the way, that all applications will receive same data from real serial port simultaneously. Shared Serial Ports can be used for serial port emulation, as it connects real serial ports by creating virtual serial ports, which are same copies as real ones. Each application will think that it is working with serial port in exclusive mode. All virtual serial ports will be able to send data to real serial port.

Virtual Serial Ports Driver XP creates two pure virtual serial ports in your system which are virtually connected to each other. For other Windows applications, virtual ports will be seen exactly as two real serial ports connected via null-modem cable. With virtual ports created by Virtual Serial Port Driver XP you can connect applications to each other and exchange data between them without occupying your real serial ports and using hardware wiring. Virtual link between virtual serial ports is much faster then real null-modem cable connection and depends on your processor speed.
