note 97613 added to function.fopen

In his note from 22-Apr-2002 08:33, jared at dctkc dot com explained how to use the serial port (thanks for that !). However, the "COMx:" notation works only for COM1 to COM9. If you need to work with ports higher than COM9, you can use the \\.\COMx notation, as shown in the following example : <?php //choose and configure COM port $comPort = "COM10"; mode $comPort: BAUD=9600 PARITY=N data=8 stop=1 xon=off; //open serial port $fp = fopen ("\\\\.\\$comPort", "w+") or die("Error opening the port"); //write on the port $string = "Hello world !\r\n"; fputs ($fp, $string); fclose ($fp); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 212.43.209.7 ---- Manual Page -- http://www.php.net/manual/en/function.fopen.php Edit -- https://master.php.net/note/edit/97613 Del: integrated -- https://master.php.net/note/delete/97613/integrated Del: useless -- https://master.php.net/note/delete/97613/useless Del: bad code -- https://master.php.net/note/delete/97613/bad+code Del: spam -- https://master.php.net/note/delete/97613/spam Del: non-english -- https://master.php.net/note/delete/97613/non-english Del: in docs -- https://master.php.net/note/delete/97613/in+docs Del: other reasons-- https://master.php.net/note/delete/97613 Reject -- https://master.php.net/note/reject/97613 Search -- https://master.php.net/manage/user-notes.php
