URGENT!!!

I'd say that it looks like the Mobile is not getting the CTL-Z. Are you sure that Hyperterminal is passing this charater through to the serial port - I don't use Hyperterminal so I don't know what it does with control characters.

Re: Trying to send SMS from PC via my Mobile using AT Comman

I had the same problem. Simply use the Break or Ctrl+Break intead of Ctrl+Z.
Despite that Break sends Ctrl+C, pressing Ctrl+C not works for me. Maybe the casue is the same as with the WinDbebug:
Note that in WinDbg, CTRL+C is a shortcut key that is used to copy text from a window. To issue a break command in WinDbg, use CTRL+BREAK or select Debug | Break from the menu.

Anyway this is nebulous for me.

Hey Guys.....

I Found the problem....

the CTRL+Z which you type in hyper terminal is unknown for Samsung D900 ((and maybe some other models)) .. JUST THIS..

so in other environments and programming languages like VB.net , C#.net,...

there is no problem and it works absolutely.!!
