Virtual Null Modem Key Features:Features :
If you have two applications you want to connect to each other using serial ports you need a null modem. A null modem is bascially a cable to connect two serial ports to each other. Normally you need two computers or two physical ports on one computer to achive this. Using Virtual Null Modem software you can emulate the null modem and run the two applications on the same computer without any additional hardware. Example: You can create two virtual serial ports: COM10 and COM12 and connect two different applications to them. Everything, that application #1 will send to COM10 will be received by application #2 at COM12, and all that application #2 sends to COM12 will be received by application #1 at COM10. Getting started is easy. Virtual Null Modem software is ready! After installing Virtual Null Modem, start it from the "Start->Programs" group.
