Nobody can help you with the little info you have provided. Can you post the code you are running?

Hi, I'm an old hand at old school RS232 links. The most common reason for jibberish is the terminal speed doesn't match what the sender is using.

Example: If the sender is sending 19200 Baud, 8 bits and your terminal app is set to 9600, you get jibber. Not an encoding issue at all.
