I am using dio functions on windows to read RS232 port.
I can read/write but it seems that the write function cannot be binary.
In particular:
<?php
dio_write($com1,chr(10),1);
?>
Will result in writing 2 bytes 0D 0A be cause \n is translated to \r\n. I have not found any way to
overcome this limitation so far
