Addendum: http://msdn.microsoft.com/en-us/library/aa363858%28VS.85%29.aspx has this to say on the matter: Communications Resources The CreateFile function can create a handle to a communications resource, such as the serial port COM1. For communications resources, the dwCreationDisposition parameter must be OPEN_EXISTING, the dwShareMode parameter must be zero (exclusive access), and the hTemplateFile parameter must be NULL. Read, write, or read/write access can be specified, and the handle can be opened for overlapped I/O. To specify a COM port number greater than 9, use the following syntax: "\\.\COM10". This syntax works for all port numbers and hardware that allows COM port numbers to be specified. For more information about communications, see <http://msdn.microsoft.com/en-us/library/aa363196%28VS.85%29.aspx>. -- PJH http://shabbleland.myminicity.com/com http://www.chavgangs.com/register.php?referer=9375
