Abstract
An application program runs on an embedded processor connected via a link to a host. When the application program identifies a need for communication over said link, it reads a pointer location to see whether its contents represent a valid address in memory, and if so the program calls that address. It then checks the code at the address to see whether an entry point is stored there, and if so uses that entry point to access a subroutine enabling communication over the link.
