This is typical of a wrong setting of serial port.
A serial port have settings and serial communication works only when the settings match on both sides.
Settings are Baud rate (speed), bits, stops ...
You can use the hyper terminal or putty to find the correct settings and debug communication.

now it is giving the following:
0020.0 0020.3 0050.0 0029.1 0100.0 0100.0 0000.0 0010.9 0000.0 0001.0 0000.0 0001.0 0000.0 0001.0 00000000000000000000000000000000
with some un-usual characters
The unusual chars can be part of the communication, you need to check the exact format of message.
