Virtual Serial Port. Serial Data Filtering and GPS Tracking.

By: Robert Thomson


Serial Data Filtering. Here is the recent case study throughly discussed at most tech forums : "Image Systems are a medium sized company who are leaders in CCTV and Point of Sale integration in New Zealand. The current solutions offered by POS providers and CCTV data capture solutions Image Systems found were limited in their functionality. Using data capture via serial ports,a system to filter out unwanted data was created". Using Virtual Serial Port Control OEM Image Systems Limited reduced the amount of hardware which is needed to filter out the data from the POS system. This has decreased time to market and decreased the cost to develop further. The Virtual Serial Port Control OEM has been included into new software using Microsoft Visual Studio 2005, written using the C# programming language.
GPS Tracking. Another case study: "VE Teltronics develops products and services for the marine industry. Our focus is on GPS tracking systems in combination with fleet management. We offer our customer innovative and cost effective solutions. We will now launch our first product, "YachtSafe". This is a complete alarm system, with tracking possibilities, and different fleet management services. The system is specially designed for charter boats. It offers different supervision features for the boat owner and the charter company. One unique feature is the Ground detection. If the boat, on a charter, hits an under water rock, it will immediately send an alarm to the boat owner. The boat owner will also receive a log, which can be used to visualize what have happen in a digital sea map in his computer. GPS data is received from the boat to the computer via the GSM network. The YachtSafe PC application will handle the incoming data and use a standard Sea map application in order to visualize the boat in a digital map. The communication between our application and the sea map application is done through a Virtual Serial Port. By using a virtual comport we have a generic way of communication, and supports most of the sea map applications on the market. The sea map applications is designed to listen to a comport for incoming GPS data, from a GPS device connected to the computer".
Virtual Serial Port Kit is an ActiveX control which makes it possible to create virtual serial ports and control them fully. At the same time virtual ports look like as if they were real hardware serial ports for communications applications. The program provides a developer with full control over virtual serial port. VSPC virtual serial port can as much as a serial device a physical serial port. Moreover, Virtual Serial Port Kit drives virtual serial port the same way as a serial device drives a physical serial port. If there is a task to provide interaction between communications application and your own program (e.g. hardware device emulator), there is no common solution to accomplish it. Virtual Serial Port Control allows to create additional virtual serial ports directly from your own program. And any communications application can work with them as if they were physical ports. On the other hand, developers API provided by the program allows your program to access the data written to virtual serial port by communications application and it also allows to respond with your own data. The data will be read by the communications application from the virtual serial port as if it were read from a physical port.
