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

Virtual Serial Port Driver XP4 creates any number of pure virtual serial ports pairs in your system which are virtually connected to each other. You can transfer files, exchange data or do whatever you want as it was real serial ports. For example, you can create virtual pair COM5-COM6. In this case all data sent by other applications to virtual serial port COM5 arrives at virtual serial port COM6 and all data sent to COM6 arrives at COM-port 5.

Serial Port Mapper allows you to map any serial ports to any other serial ports. For example you install additional serial port expansion card to computer as COM7 serial port but your favorite software can work with COM1...COM4 ports only. To resolve this problem you can use Serial Port Mapper to map new COM7 port either to COM1 or to COM2...COM4. Now your software can open COM1 port (or COM2...COM4) but actually work with new COM7 port.

Serial Port Redirector is used to connect a serial application to a remote TCP socket. This allows you to utilize modern hardware COM servers without changing your software or exchange data between a TCP/IP application and an old-fashioned program that can only connect to a serial port. This is done by creating virtual COM ports. Virtual COM ports accept connections from serial applications and redirect the data to a specified IP address/port.

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.

This is software-based solution that lets you share up to 255 serial port devices over TCP/IP network. So, any serial port device connected to COM port could be accessed from anywhere as if it is attached to local PC. It provides the ability to create three different types of connection: Port-to-port, Port-to-TCP client and Port-to-TCP server. Serial to Ethernet Connector uses virtual port technology which emulates real serial ports.
