    摘要: A system for transferring solicited message packets between data processors coupled on a serial communications path. A solicitor processor allocates a portion of its memory for storage of solicited message packets which might be solicited and received from at least one other data processor. The solicitor data processor defines a sequence of operations to be performed on any such received solicited message packets at that processor. The solicitor processor also transfers a solicited message parameter signal to the solicitee data processor where that signal is representative of a predetermined header portion for solicited data packets which might be generated by the solicitee data processor and transferred to the solicitor data processor. The header portion of a solicited message packet relates one or more of the sequences of operations which are to be associated with that packet. At least one of the other data processors receives any solicited message parameter signal addressed to that solicitee data processor. The solicitee processor is responsive to a received message parameter signal to generate a solicited message packet (with a header portion, as defined by the solicited message parameter signal) for transfer to the solicitor processor. The solicitor processor receives any such transmitted solicited message packet and stores that packet in the allocated portion of memory.
