Abstract
A "Personal Computer Memory Card International Association" (PCMCIA) peripheral, e.g., a modem, incorporates a shared memory interface to a personal computer. This shared memory interface provides the capability to easily program the PCMCIA peripheral either in the factory or in the field. In addition, the shared memory interface removes the requirement of having a resident "boot-up" code in the PCMCIA peripheral. Finally, the shared memory interface provides the capability to transfer user data from the personal computer, i.e., data terminal, to the PCMCIA modem at a higher data transfer rate than is currently available via the modem's universal asynchronous receive/transmit (UART) integrated circuit.
