  • Patent number: 5303349
    Abstract: A computer interface having time frame dependent functional designation of parallel port lines system. A communication cycle is established with a plurality of time frames for a group of parallel port lines. Discrete data bytes are transferred to and from a computer, during at least one of the time frames and data blocks are transferred, to and from the computer, during at least one other of the time frames. The designation of the parallel port lines is redefined during each of the time frames to accommodate the transfers to and from the computer of the discrete data bytes and data blocks. Discrete data bytes and data blocks to be sent and received are stored and this storing is conditioned as a function of the designation of the parallel port lines during each of the time frames.
