Abstract

Systems and methods are described for reliably transmitting data in a network. The method includes: performing by a module, monitoring data from an output drive module for errors; and when an error is detected, generating a first signal based on the monitoring, and adjusting an input voltage to at least one of a pull-up resistor and a pull-down resistor for a predetermined time based on the first signal, to emphasize the error.
