I am using a LED display which has following specifications:

TFI-32x128-37RG 4.76mm Tri-color RS232/Ethernet   6.9"x26.22"x2" 4
lines of English

I have connected it to PC com port and want to send data through the
port.
But when I use hyperterminal to send some data on the LED board, it is not
responding. 
Is it possible to send data through hyperterminal on LED board?
Or is there any other method to display data on LED board through PC com
port?

Presumably, yes, if you're using the right baud and character settings
(bits/character, parity, stop bits). However, the interactions between
Hyperterminal, RTS/CTS, DSR/DTR, and the LED board may also be an issue.
You might want to try TeraTerm http://en.wikipedia.org/wiki/TeraTerm

I assume you've reviewed the documentation available at

As Rich wrote, you need to find out what baud rate, start/stop bits and 
hardware handshakes this display expects. This information should be in 
the booklet that came with it or maybe online at the manufacturer's site.

Not to spoil the broth here but there can also be electrical 
discrepancies. For example one of the laptops here has a hard time 
driving some RS232 devices. A voltmeter revealed it: The laptop only 
sends a 6V level and some devices don't seem happy with that (although 
per standard they should).
