1. A method of operating a serial buffer having a first port that implements a first protocol and a second port that implements a second protocol, different than the first protocol, the method comprising:

  • receiving a first request packet consistent with the first protocol on the first port, the first request packet having a first identification value;

    associating the first identification value with a corresponding second identification value that is compatible with the second protocol;

    modifying the first request packet to include the second identification value;

    transmitting the modified first request packet to the second port;

    receiving a first response packet including the second identification value on the second port, wherein the first response packet is provided in response to the modified first request packet;

    associating the second identification value of the first response packet with the first identification value;

    modifying the first response packet to include the first identification value; and

    transmitting the modified first response packet to the first port.
