Claim 1
Independent Claim
186 words
A method for serially transmitting a composite parallel frame between stations terminating local and remote parallel buses with a serial link therebetween comprising, receiving a parallel frame at a local station, decomposing the parallel frame into a data sub-frame and a management sub-frame, said management sub-frame including management bits from said parallel frame and a three bit local message for handshaking between stations, the three bits indicating the following states: ready for data, new byte available, and ready for next byte, tagging said sub-frames with message codes to enable said stations to distinguish data sub-frames from management sub-frames, serially transmitting a management sub-frame from the local to the remote station, said three bit local message of said management sub-frame indicating a new byte available, then receiving a serially transmitted management sub-frame from the remote station at the local station, said three bit local message of said management sub-frame indicating ready for data, then serially transmitting a data sub-frame from the local to the remote station and then receiving a serially transmitted management sub-frame from the remote station at the local station acknowledging the data sub-frame received.
Claim 2
Independent Claim
186 words
A method for serially transmitting a composite parallel frame between stations terminating local and remote parallel buses with a serial link therebetween comprising, receiving a parallel frame at a local station, decomposing the parallel frame into a data sub-frame and a management sub-frame, said management sub-frame including management bits from said parallel frame and a three bit local message for handshaking between stations, the three bits indicating the following states: ready for data, new byte available, and ready for next byte, tagging said sub-frames with message codes to enable said stations to distinguish data sub-frames from management sub-frames, serially transmitting a management sub-frame from the local to the remote station, said three bit local message of said management sub-frame indicating a new byte available, then receiving a serially transmitted management sub-frame from the remote station at the local station, said three bit local message of said management sub-frame indicating ready for data, then serially transmitting a data sub-frame from the local to the remote station and then receiving a serially transmitted management sub-frame from the remote station at the local station acknowledging the data sub-frame received.
Claim 3
Dependent Claim
34 words
The method of claim 1 further defined by transmitting an error sub-frame from one of said stations to another station, in response to an error condition, said error sub-frame tagged with a message code.
Claim 4
Dependent Claim
27 words
The method of claim 2 further defined by transmitting from one station the prior data sub-frame in response to receipt at said station of an error sub-frame.
Claim 5
Dependent Claim
32 words
The method of claim 1 further defined by reconstructing at the remote station parallel frames for transfer on a data bus, the parallel frame including information from said data and management sub-frames.
Claim 6
Dependent Claim
22 words
The method of claim 1 wherein each sub-frame comprises at least a start bit, message code bits, and data or management bits.
Claim 7
Dependent Claim
20 words
The method of claim 1 further defined by transmitting from one station to another station on command, a poll pattern.
