Many software applications have been written to communicate with devices that are directly connected to a server’s serial COM port. Companies want to network enable these applications because the devices that were directly connected to the servers COM ports need to be moved to a remote location some distance way from the application server. Since the original application was designed to talk directly to a specific COM port, a solution, which is seamless to both the application and device, must be implemented to enable communication across an IP network infrastructure. In other words, a solution that makes the application think is talking directly to the COM port is required. People often refer to this as creating a ' virtual serial port' or creating a ' virtual COM port'. TruePort software, used with Perle and provides an ideal solution.

All COM port directed data sent by the application is re-directed by TruePort across the IP/Ethernet network to remote Perle or which have the target devices connected to them. Data and serial port signaling is transparently communicated between the application and remote device. Many organizations run these applications on various server platforms. While other Terminal Server vendors provide a COM port redirector that is limited to the Windows operating systems, Perle’s TruePort provides a comprehensive driver set supporting Windows, Linux and Unix operating systems..

As long as the attached device is within the limited distance reach of the PC, this works great. But, the moment the device is placed on an Ethernet network and direct serial connection is broken, the ability of the application software to communicate with the device is lost. That's where Com Port Redirector comes in.
