SCSI is a serial system, or at least it can be.
Pardon? Usually, when one has a data bus for several parallel data
lines at once, one refers to it as parallel.
Serial - one data line, that sends bits sequentially.
Parallel - several data lines, that send bits simultaneously.
Of course its never that simple. Most "serial" busses are actually
multiple wires which send information in parallel..
More likely
txdata
rxdata
Maybe a pair for the other direction (eg RS0232C)
