Thank you for the replies.

I am trying to change the parity on the TTL port.

I am sure I need to change parity in order to do what i need to do. If you want I can upload the serial API that I wrote for the laptop that I am using to communicate to the RC(through an IR). [Tested the parity with Hyper Terminal communicating through the same IR but this time from the laptop to a PC, only even parity works].

EDIT: I was able to get the RC and laptop to sent signals, just with a problem the RC was giving a error value(255) . [It printed "other Data" only at start and shut down of the RC (on IFI Loader terminal), I made it print the "other Data" as an integer which was 255]
