To emulate null-modem connection Virtual Null Modem can be effectively used. The program emulates one or more couples of RS-232 serial ports connected via virtual null-modem cable. It is possible to create the unlimited couples of VSP on a single PC without additional hardware and connect them in any sequence using virtual null-modem cable. Usually you need to use virtual null-modem when you have two applications to be connected via serial ports.

To monitor (bi-directional) Serial communication RS-232 between two devices without physical cable, you can use the freeware Bill Serial Monitor. This freeware enable you to view, log, test and analyse the activity of the serial RS-232 port. If you want to monitor the serial protocol of two different serial devices you can use our Protocol Analyser function. DSR, CTS, DTR and RTS can also be controlled

Free software serial port monitor, Com Rs232 sniffer with communication packet data analyzer. This monitoring utility can spy, capture, view, analyze, test com ports activity performing com port connection and traffic analysis with data acquisition and control. You can use this system as device interface testing tool, modem data transfer viewer and so on.

Virtual Serial Port ActiveX CE is a powerful ActiveX Control for Embedded platforms that allows your software to create custom additional virtual serial ports in Windows CE system and fully control them from within your own program. Virtual serial ports you will create look and work absolutely like real serial ports for other Windows CE applications. VSP ActiveX Control CE features unique set of algorithms for system and port events notification.

Docklight is a test, analysis and simulation tool for serial communication protocols (RS232, RS485/422 and others). It allows you to monitor the communication between two serial devices or to test the serial communication of a single device. Key functions include: * Simulating serial protocols * Logging RS232 data * Detecting specific data sequences * Responding to incoming data.

Docklight Scripting is an extended edition of Docklight RS232 Terminal / RS232 Monitor. It features an easy-to-use script language, plus a built-in editor to create and run automated test jobs. A Docklight script allows you to execute all basic Docklight functions (sending predefined data sequences, detecting specific sequences within the incoming data stream, ...) and embed them in your own test code.

Many powerful electronic devices can be connected to a PC through an RS232 interface. However, most are virtually useless without good accompanying software. ByteWedge by Fogsoft supports a wide range of devices, from lab equipment to office telephone systems. It can collect data from devices and input it directly into your database, whether it is MS Access, MySQL or any other ODBC-compliant database.

Serial Port Monitor is a system utility for exploring the way OS works and monitoring how applications use ports. It can effectively be used for monitoring serial data exchange between serial devices and any Windows application, debugging computer connection with peripheral devices using COM port, for solving problems with serial (RS232/422/485) data communication control networks and devices, for software and hardware testing etc.
