Claim One:
1. In a device that communicates over a communications interface having a plurality of channels with communications according to a vector signaling code, a method of adjusting and controlling the communications interface comprising: measuring a signal level of each of a measured plurality of the channels; comparing signal levels between a first set of pairs of the measured plurality of the channels to form a first set of comparisons; comparing signal levels between a second set of pairs of the measured plurality of the channels, wherein the second set is not identical to the first set, to form a second set of comparisons; reading data that maps data patterns of the first set of comparisons and the second set of comparisons to corresponding identified secondary communication characteristics, such that a data pattern is deemed likely to be sensitive to its corresponding identified secondary communication characteristic; identifying at least one data pattern and its corresponding identified secondary communication characteristic; determining a metric for the identified secondary communications characteristic using signal levels associated with its corresponding data pattern; and outputting one or more instructions that, when received, would cause the communications interface to adjust the identified secondary communications characteristic.
