Null-modem Software

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.

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.

Advanced Serial Port Terminal is a great tool for developers that lets connect to any number of serial ports (including virtual ones) or to remote computer using null modem cable. The application lets you open as many serial ports as you like; dynamically change serial port settings without closing and reopening current port; adjust baudrate, databits, stop bits, flow control parameters; save all received bytes into a file and do lots more.

Modem Monitor is a program for monitoring a status and performance of the remote(or local) modem. The program is intended for using in networks, connected to Internet through phone line(modem). Allows on workstations in the network to receive the information about status and performance of the modem connection, located on other machine. Designed in client - server distributed architecture.

Network Virtual Serial Ports Driver is an advanced utility, the purpose of which is to emulate null-modem cable on computers located in a TCP/IP LAN or connected to the Internet. In other words, with VSPD Net you can create any number of pure virtual serial ports in your system, which will be connected over TCP/IP network to another computer via virtual null-modem cable. Real serial ports will not be occupied.

Acesms ActiveX SDK is a great tool to send /receive Unicode SMS via GSM phone or Modem from windows system,AceSMS ActiveX is designed to work with a wide range of phones (Nokia: Siemens:MotoFalcom: GSM Modem Wavcom Modem TC35 Modem AceSMS ActiveX is based on a widely accepted Technical Specification known as : GSM0705 All phone and modem support GSM0705 GSM0340 can use this controls to receive/send Unicode SMS,write/read Unicode PhoneBook

Advanced Virtual COM Port is the first software of its kind which includes both local and network virtual COM port functions. It can share your real COM ports or create virtual COM ports and connect them with a virtual null-modem cable locally or through the network. You can connect to a shared port and use it just like it is on your machine. Virtual serial ports created by the program look and work the same way real ones look and work.

Virtual Serial Port Kit creates pairs of virtual serial ports in your system which are virtually connected to each other. Physical null modem cables are not required. You can connect any number of virtual port pairs. Virtual serial port pairs will look and work exactly like real hardware serial ports connected via null modem cables.Virtual Serial Port Kit is designed for software developer to speed up development process during software debugging

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.

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.
