Abstract
A messaging peripheral (100) includes a processor (106) for executing a microcode program that controls operation of the messaging peripheral (100), and a PCMCIA memory only interface (119) that allows communication of communication of at least one message and a user selectable password between an electronic information processing device (200) and the messaging peripheral (100). The PCMCIA memory only interface couples to a secure memory access interface that is controlled by the processor (106). The secure memory access interface (703) allows the electronic information processing device (200) to access the at least one message when a memory protection mode is selected and the processor (106) receives a user entered password and performs a correlation between the user entered password and the user selectable password.
