hi... i have the same question too. have you already found the answer for this?

hi peter, finally i've made it with visual c++ 6.0 but, this is will only success if i use windows XP as the operating system, and failed when i try those in win2000pro or win 2000 server. maybe i should told you that my irda device can only be attached to the usb, not to the serial port. so i can't use my code to send or recieve any information. and maybe you can told me for the suitable path that i can use for accesing this usb irda device, instead of com3 that will only automatically show up (added to the com port list) when i beam my cellphone's irda in windows XP OS not to win 2000. i have try what you told to write IRDAx as the path but this's failed please help me :( thank's very much! note: i also email you this post.;)

hi peter, i have try again and it works,the programm can detect my irda device on com3. but when i start to send the AT Command to the phone by using WriteFile function, there's no reaction. and then i want to translate the working code into VB.net, but the result will not correctly why???:confused: can you help me????please:(

Hi Peter, I'm a begginer in this, i know that this section is For C++ only, but I have the same problem to comunicate to my cell phone, and I'm very confused now. I have already try CreateFile,ReadFile,and WriteFile Function as you tell us on this message board. I try those using Visual Basic by declaring CreateFile Function with kernel32.dll as the library. the problem is there is no file created when the programm's running, even on my drive C:\. this is my code. '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' CF=CreteFile("C:\tester.txt",GENERIC_WRITE, _ FILE_SHARE_READ,0,CREATE_NEW,FILE_ATTRIBUTE_ARCHIVE,0) if CF<>-1 then 'write file function else msgbox "Error Message" end if CloseHandle(CF) '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' I have try to change the first parameter with "\\.\c:\tester.txt" or "\\.\irda1\tester.txt" but the result is same, there's nothing happen. I hope you can give me a sugestion or maybe you can tell me where i can find the example programm in VB or VB.NET Thank you Very Much!!! and im sory, my english is not very good;P
