Claim:
1. A method of automated adaptation of a transmitter equalizer, the method comprising: dividing a multi-dimensional search space of tap settings for the transmitter equalizer into multiple single-dimensional search spaces, each single-dimensional search space being associated with a single tap of the transmitter equalizer; searching the multiple single-dimensional search spaces in series; and setting a tap for a single-dimensional search space before searching a next single-dimensional search space, wherein searching a single-dimensional search space comprises finding a tap value which corresponds to a minimum bit error rate, and wherein finding the tap value which corresponds to the minimum bit error rate comprises: decrementing a current tap value to a next lower value; finding a current bit error count for the current tap value; comparing the current bit error count for the current tap value with a saved bit error count stored in a register; replacing the saved bit error count with the current bit error count if the current bit error count is less than the saved bit error count; and incrementing a boundary count if the current bit error count is equal to the saved bit error count.
