note 95845 added to function.fopen

Hello, I tried to use this example: mode com1: BAUD=9600 PARITY=N data=8 stop=1 xon=off; $fp = fopen ("COM1:", "w+"); if (!$fp) { echo "Uh-oh. Port not opened."; } else { $string = '1234567890'; //or any other string fputs ($fp, $string ); fclose ($fp); } to write to a port or read from a port but I get error: 'unable to bind...' or 'connection fail. the connection was not respoding in time...'. What do I do wrong? ---- Server IP: 69.147.83.197 Probable Submitter: 85.250.225.224 ---- Manual Page -- http://www.php.net/manual/en/function.fopen.php Edit -- https://master.php.net/note/edit/95845 Del: integrated -- https://master.php.net/note/delete/95845/integrated Del: useless -- https://master.php.net/note/delete/95845/useless Del: bad code -- https://master.php.net/note/delete/95845/bad+code Del: spam -- https://master.php.net/note/delete/95845/spam Del: non-english -- https://master.php.net/note/delete/95845/non-english Del: in docs -- https://master.php.net/note/delete/95845/in+docs Del: other reasons-- https://master.php.net/note/delete/95845 Reject -- https://master.php.net/note/reject/95845 Search -- https://master.php.net/manage/user-notes.php
