problem in the IR communication using the RAW IR

[Guest Angel2000]

:cry: Dears

I am facing probelm with my device which is runing on wince .NET . I wrote an application to use the RAW IR method. I can open the IR OK and I can receive the data OK from my other Hardware device. I am using the writefile,createfile and readfile for my work. My problem is that I am sending one byte at a time and when I send the byte I see the my PDA device automaticaly send the ascii code 0x7F (DEL) with my original byte which prevent me from getting my original sent byte in my other hardware because they are sent quicly. I have checked the writefile function and I saw that It only send the byte I gave it which make me very crazy on were this extra byte came from. I tested my code on normal serial and It was working perfect and the only problem is when I use it for the RAW IR. My RAW IR is port COM4. So please if someone has a solution that he can help me in. Thanks
