Abstract:
A system, comprising:a processor configured to execute instructions;modem software accessible by the processor and comprising instructions executable by the processor;an interface coupled to said processor and configured to transmit and receive signals over a data line in response to commands generated by the processor when the processor is executing the instructions of the modem software;wherein the modem software is configured to:determine a first measure of a utilization of the processor before a beginning of a data transfer operation via the interface;negotiate a data transfer bit rate for the data transfer operation dependent upon the first measure of the utilization of the processor before the beginning of the data transfer operation;determine a second measure of the utilization of the processor during the data transfer operation; andnegotiate a change in the data transfer bit rate for the data transfer operation during the data transfer operation dependent upon a difference between the first and second measures of the utilization of the processor.
