Sharing information between a host computer system and a peripheral computer system. Conduit programs running simultaneously on the host computer system synchronize information between the two computer systems. The conduits initiate multiple time multiplexed transfers across a single communication link between the two computer systems. In general, one or more conduits can perform a non-transfer task while another conduit can simultaneously perform a transfer over the host-peripheral communication link. The conduits may be used to load software onto the peripheral computer or to exchange e-mail between the two computer systems. While one active conduit is performing a task that does not involve use of the communication link, the other simultaneously executing conduits can use the communication link to transfer records between the host and the peripheral computer system.
