need help with a remote control program on Nokia 3650

I have modified the IRScope program [url=http://newlc.com/Programming-IrComm3-wire-raw.html] that is available on the newlc
website. I have eliminated the read from the program and sending the bytes directly to the write. I am trying to make it work with
the Sony triniton having the remote RM783.

I am sending the volume- signal described at [url=http://www.sbprojects.com/knowledge/ir/sirc.htm]

I am using Visual .net 2003 IDE with Carbide.vs plugin.

The main problem is that I can not figure out what to write in the write() method.
I changed that write so many times. I learned that comb of 0xdb pulses at [url=http://www.veg.nildram.co.uk/remote.htm] (Search for 0xdb on the page) could do the work.

the article states:
"I make the assumption that most receivers will be happy with combs of pulses at 38.4kHz, since they are designed round R-C
filters and diode pumps (at least conceptually, though most use one integrated device). I can achieve this by transmitting
suitable characters at 115200 baud out of any serial port, so long as there are no gaps between characters. The precise pattern
for a comb is the character value 0xdb, at 115k2/8/e/2 (0x5b at 115k2/7/n/1"

i have a question here... it is about the character value ... what will the write statement have in its parameter ... a string ? or a buffer and what will be its value ?

I am attaching the zipped file of the source and the header file. Please if some kind soul can see what Wrong I am doing here.
Most probably i think there is some problem with the write() method only.
Does anyone know what exactly in the code I have to write so that it can work.
It has been so many days but I am still not able to make it work with that. Please anyone help me with this program. I really do not know what wrong i am doing in it. I have been stuck with it for so many days.

code snippet of our program:
