ABSTRACT:
A method and apparatus for transmitting encoded data from one computer system to another using an AT command set compatible communication device is described. Data being sent from a communications application to the AT command set compatible communication device is monitored, and encryption is performed in response to detecting a connect message and a carrier detect signal received from the communication device and changing in response to said detection the state of an encryption application from a first state to a remote state and the data is encrypted using a stream encryption scheme before it is passed to the communication device. When a break sequence is detected or a carrier detect signal is deasserted, encryption is ceased thus having the encryption application automatically return to the first state.
