24. A system to interface with a communication channel having a plurality of serial data lanes, comprising: receivers to receive serial data from the serial data lanes, each receiver of the receivers including a serial-to-parallel converter to convert the serial data received to a parallel format; the receivers providing outputs that collectively form a word having a width related to a total number of the serial data lanes; decoders configured to identify character types recovered by the receivers; logic configured to determine when a decoder of the decoders has identified at least one of the character types of a group consisting of a start-of-frame (SOF) character and an end-of-frame (EOF) character; parsing circuitry configured to parse valid characters of the word based upon placement relative to the at least one of the character types identified; storage registers selectively operable to store the valid characters; and a controller to control presentment of the valid characters parsed as valid data to at least one of the storage registers and an output port, the presentment of the valid characters based on the character types identified by the decoders, placements of the SOF character, a first amount of the valid characters parsed by the parsing circuitry, and a second amount of the valid characters stored in the storage registers; and a generator configured to provide a first sideband signal associated with the valid data for output as sideband encapsulated, the first sideband signal being responsive to the SOF character.
25. The system of claim 24 , wherein the generator is configured to present the first sideband signal as a sideband start-of-frame (SOF) signal to accompany the valid data at the output port when first presented.
