A method of providing an enhanced reverse link encapsulation packet over a transmission link that couples a client and a host within an electronic device, comprising the steps of: setting a first flag within the enhanced reverse link encapsulation packet and transmitting the flag from the host to the client requesting that a synchronization pattern be transmitted from client to the host; setting a second flag within the enhanced reverse link encapsulation packet and transmitting the flag from the host to the client requesting a byte count of a number of bytes to be transmitted from the client to the host; providing a fixed period of time within the enhanced reverse link encapsulation packet for the host to disable its driver outputs on the transmission link; providing the synchronization pattern transmitted by the client in a reverse data portion of the enhanced reverse link encapsulation packet; providing the byte count within the reverse data portion of the enhanced reverse link encapsulation packet indicating a total number of bytes expected to be transmitted from the client to the host; and measuring a round trip delay between the host and the client using the synchronization pattern, the method characterized by: providing a turn-around to allow the remaining amount of data from the reverse data portion to be transmitted from the client; aligning the host with the enhanced reverse link encapsulation packet based on the round trip delay and the synchronization pattern; and sending a byte count value from the client to the host indicating the client will send fewer bytes than currently allocated in a reverse data portion of the enhanced reverse link encapsulation packet, wherein the byte count value is no larger than the value indicated within a maximum bytes field of the enhanced reverse link encapsulation packet. setting a first flag within the enhanced reverse link encapsulation packet and transmitting the flag from the host to the client requesting that a synchronization pattern be transmitted from client to the host; setting a second flag within the enhanced reverse link encapsulation packet and transmitting the flag from the host to the client requesting a byte count of a number of bytes to be transmitted from the client to the host; providing a fixed period of time within the enhanced reverse link encapsulation packet for the host to disable its driver outputs on the transmission link; providing the synchronization pattern transmitted by the client in a reverse data portion of the enhanced reverse link encapsulation packet; providing the byte count within the reverse data portion of the enhanced reverse link encapsulation packet indicating a total number of bytes expected to be transmitted from the client to the host; and measuring a round trip delay between the host and the client using the synchronization pattern, the method characterized by: providing a turn-around to allow the remaining amount of data from the reverse data portion to be transmitted from the client; aligning the host with the enhanced reverse link encapsulation packet based on the round trip delay and the synchronization pattern; and sending a byte count value from the client to the host indicating the client will send fewer bytes than currently allocated in a reverse data portion of the enhanced reverse link encapsulation packet, wherein the byte count value is no larger than the value indicated within a maximum bytes field of the enhanced reverse link encapsulation packet. providing a turn-around to allow the remaining amount of data from the reverse data portion to be transmitted from the client; aligning the host with the enhanced reverse link encapsulation packet based on the round trip delay and the synchronization pattern; and sending a byte count value from the client to the host indicating the client will send fewer bytes than currently allocated in a reverse data portion of the enhanced reverse link encapsulation packet, wherein the byte count value is no larger than the value indicated within a maximum bytes field of the enhanced reverse link encapsulation packet.
