Please Help, I'm having a very strange problem, sometimes my 
application is "Freezing" in the following command - 

WriteFile( hndl, TxBuff, MessageLen, &written, NULL ); 

(sending data through RS-232 port)

sometimes it's happening after 15 seconds, and sometimes after 2
minutes.... I checked the command parameters and they all looks
OK, I compared the command parameters (hndl, TxBuff...) when the
command works OK, and when it's freezing, and they looks exactly 
the same..... what can be the problem ?? 

Thanks! 

Ramy.
