I was burning a program to read inputs from a sensor and drive a speaker if the input would fall below a threshold and was also monitoring the input on the serial monitor. After a few times of running the code suddenly Arduino refused to pragram. I restarted my computer and tried again but still it won't program. Can anybody interpret the error that I have posted below and tell me what is the matter.

Also, the last program that I had burnt is still working on the arduino.

Sorry everyone. Got the solution here.

Try editing your Arduino preferences file (~/.arduino/preferences.txt I think) and setting the serial.debug_rate to, say, 9600.  (serial.download_rate should be 19200).
