Abstract

A method and system that allows a host system application to securely communicate with a legacy device is provided. A redirector software module receives data that is destined for a host system serial COM port. Data is secured and re-directed to a legacy device via a network port instead of the serial COM port. Conversely, data destined for the host system is provided to a device server via a server COM port by the legacy serial device. The data can be encrypted and sent to the host system via the network. The redirector software module decrypts the encrypted data and presents it to the consumer application as if the data had arrived via the local COM port.
