Claim:
1. A method of negotiating a communication channel between transceivers, the method comprising: as part of a first stage of a channel negotiation between a first transceiver and a second transceiver, exchanging information between the first and second transceiver over the communication channel in a reduced speed mode, wherein the first stage of channel negotiation further comprises determining an amount of skew that is present on at least one differential signal pair between the first and second transceivers, and adjusting transmission over the at least one differential signal pair to account for the determined amount of skew; as part of a second stage of the channel negotiation subsequent to the first stage, adaptively acquiring at least one parameter associated with the communication channel; and exchanging information between the first and second transceivers for use in the channel negotiation; and as part of a third stage of the channel negotiation subsequent to the second stage, entering a full functional mode in which information is exchanged between the first and second transceivers using multi-level modulation.
