Abstract
A partial emulation technique in which only the answers to poll frames and uplink information frames, or the slave part of the protocol, are emulated. All messages from the processor are passed down-link, and emulation is dependent upon the contents of an attendant list (452). In operation, the attendant list (452) is built by detecting responses to poll frames from the main controller (401). Once entries are made in the attendant list, partial emulation of responses to down link poll frames and up link information frames for each entry is allowed. No emulation of down link information frames occurs.
