Null-modem cable is basically used for communication of two RS-232 DTE devices with each other. To create null-modem connector between the devices you demand to usance two computers or two successive ports of a single computer connected with null-modem cable. The both methods described above are expensive and difficult because of many reasons. The most reliable way to create null-modem connector is using of virtual successive ports emulated by virtual successive port driver and null-modem cable. Why do you demand to emulate successive ports and null-modem connector? There are few main reasons to do it. Firstly, you don't demand to birth two computers connected with real null-modem cable. Secondly, there's no demand in a single PC with several unblock successive ports and additional multi successive port devices which are expensive and bulky. To emulate null-modem connector Virtual Null Modem fundament be effectively used. The program emulates one or more couples of RS-232 successive ports connected via virtual null-modem cable. It is possible to create the unlimited couples of virtual successive ports on a single PC and connect them in any sequence using virtual null-modem cable. Usually you demand to usance virtual null-modem when you birth two applications to be connected via successive ports. In contrast to ordinary connector you do not demand any additional hardware (computers, physical successive ports, cables) to perform it. Virtual null-modem allows user emulate virtual cipher modem connector and rill the two applications simultaneously on the same computer. Moreover, it is possible to emulate real-world situations by adding some errors to the data convert which may occur during the physical null-modem connector. Owing to its features laid Virtual Null Modem fundament sufficiently rest the shape of software developers and testers occupied in the field of industrial automation. Furthermore, the program may also be useful in the reverse engineering as considerably as in educational needs. So go beforehand and download FREE test version today!
