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.

Claims

1. A method of reliably transmitting data in a network, comprising:

performing by a module,

monitoring data from an output drive module for errors before the data is to be transmitted on a communication bus; 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.

2. The method of claim 1 wherein the monitoring the data of the output drive module comprises monitoring data of a data packet bit by bit.

3. The method of claim 1 wherein the predetermined time includes a time to complete the remainder of the transmission of the data.

4. The method of claim 1 wherein the adjusting the input voltage is to the pull-up resistor that is external to the output drive module.

5. The method of claim 4 wherein the adjusting the input voltage is further to the pull-down resistor that is external to the output drive module.

6. The method of claim 1 wherein the adjusting the input voltage is to the pull-down resistor that is external to the output drive module.

7. A system for reliably transmitting data, comprising:

an output drive module; and

a monitoring module that monitors data from the output drive module for errors before the data is to be transmitted on a communication bus, and that when an error is detected, generates a first signal based on the monitoring, and adjusts 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.

8. The system of claim 7 wherein the monitoring module monitors the data of a data packet bit by bit.

9. The system of claim 7 wherein the predetermined time includes a time to complete the remainder of the transmission of the data.

10. The system of claim 7 wherein the monitoring module adjusts the input voltage to the pull-up resistor that is external to the output drive module.

11. The system of claim 10 wherein the monitoring module adjusts the input voltage further to the pull-down resistor that is external to the output drive module.

12. The system of claim 7 wherein the monitoring module adjusts the input voltage to the pull-down resistor that is external to the output drive module.

13. A computer program product for reliably transmitting data in a network, comprising:

a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising;

monitoring data from an output drive module for errors before the data is to be transmitted on a communication bus;

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.

14. The computer program product of claim 13 wherein the monitoring the data of the output drive module comprises monitoring data of a data packet bit by bit.

15. The computer program product of claim 13 wherein the predetermined time includes a time to complete the remainder of the transmission of the data.

16. The computer program product of claim 13 wherein the adjusting the input voltage is to the pull-up resistor that is external to the output drive module.

17. The computer program product of claim 16 wherein the adjusting the input voltage is further to the pull-down resistor that is external to the output drive module.

18. The computer program product of claim 13 wherein the adjusting the input voltage is to the pull-down resistor that is external to the output drive module.
