To monitor (bi-directional) Serial communication RS-232 between two devices without physical cable, use Bill Serial Monitor. This software allows you to view, log, test and analyse the activity of the serial RS-232 port. To monitor the serial protocol of two different serial devices. DSR, CTS, DTR and RTS can also be controlled
No programming or additional hardware required !

You can connect data collection serial devices: bar code scanners, modems, sensors, gages, RF equipment, telephone PBX systems, laboratory or industrial instruments, and so on - to the serial ports of your computer to deliver that data anywhere over any TCP/IP based network. Program creates up to 254 virtual serial ports at a time. Physical COM ports located on remote computer can be connected to host computer over the network as well.

The TGetDiskSerial is a VCL component. You can use it to read the serial number of hard disk easily. As we all know, this serial number is unique in the world. So this component is of great use, for example, you can use this serial number to creat an encrypt number.

Eltima Serial Port Terminal is an ideal tool for testing, debugging and troubleshooting serial port devices. It lets you work with numerous number of ports simultaneously, both serial and virtual ones. You can easily alter baudrate, databits, parity, stop bits, flow control parameters and dynamically apply these changes to serial port settings on the go. You can always check for history of typed commands.

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

With Virtual Serial Port Driver CE you can connect one application to another using virtual serial ports pair for instantl data transfer. VSPD CE creates two pure virtual serial ports in your system which are virtually connected to each other. Virtual serial ports look and work exactly as two real serial ports connected via null-modem cable for Windows CE applications. Compatible with any Windows Mobile device with OS up to WindowsCE 5.0

Create and manage virtual serial ports from .NET and Visual Basic (ActiveX)
Using Virtual Serial Port SDK you can create a "new" serial port on your computer. This serial port is completely controlled by your application. Other 3rd party applications can connect to this serial port and believe it is a normal serial port.
Windows Mobile/Pocket PC, Windows XP/2k/NT and Windows ME/98.
Samples in C#, VB.NET and VB6

Shared Serial Port - advanced utility to share real serial ports between applications so that all applications will receive/send data from/to real serial port simultaneously. Shared Serial Port creates virtual serial ports, which are same copies as real ones. Any virtual serial port will have the same name as the real one and any number of applications will be capable of using it at the same time.

Virtual Serial Port Driver XP (VSPD XP) creates virtual com ports in your system and connects them via reliable virtual link, which emulates real null-modem cable. With VSPD XP you can connect one application to another using virtual serial ports pair. Applications will be able to exchange data. The latest version of VSPD XP now supports full baudrate emulation. New manual and examples are available.

AlarIT Virtual Serial Driver is appointed for emulation of one, two or more (up to
200) serial streams. Hardware devices are not necessary. This product is
based on Windows XP DDK and doesn't require using devices of other
manufacturers. The whole product is created with the help of Microsoft tooling.

Serial Port ActiveX Control is a powerful component that lets developers quickly and effectively work with serial port. Use Serial Port component to easily communicate with external devices on RS232 connection, such as modems, bar code readers, PBX and so on. Serial Port introduces several extremely useful properties for detailed setting of serial port, numerous methods to write and read from port and events to control serial port state changes.

Share Serial Ports is an advanced utility for sharing real serial ports between multiple applications so that all applications will receive same data from real serial port simultaneously. It is achieved by creating virtual serial ports, exact copies of real ones. All virtual ports can send data to real serial port. You will be able to set port permissions to read, write or change control lines state for every application separately.

Serial Splitter is an application, based on Windows kernel drivers technology and Eltima Virtual Serial Ports Driver. It allows you to share real serial port between several applications in a way that all applications will receive same data from one serial port simultaneously. It is achieved by creating virtual serial ports, which are same copies of real ones. Each application will think that it is working with serial port in exclusive mode.

Serial Splitter CE splits real serial ports into virtual ones. It is really useful if you need several applications to work with the same serial port on your mobile device (several apps to read from one GPS device). With Serial Splitter CE one program works with one virtual port, the other one with another port, etc., but in fact all of them work with the same split real port. You can create up to 20 equal virtual ports for splitting real ports.
