This PHP program generates an HTML form which you can use to create a TCP socket to a remote device and send data to it. This assumes the remote device accepts the socket connection on the port you choose to connect to.<\/p>\n

On submit, the form will call itself and then check to see if the form element ‘text1’ is set. If set a socket is made to the define IP address and port and the value of ‘text1’ is sent down the pipe.The socket then disconnects and the form is redisplayed with the value of ‘text1′ in the html form’s textbox.IMPORTANT: If you are using an XPORT or COBOX change the connect mode to C4so no IP address is being concatenating with the incoming message to the pic….unless you like it that way.*\/$xportIP = “128.122.151.44”; \/\/IP adddress to connect to$port = 10001; \/\/ port number of IPif ((isset($_POST[“text1”])) && (isset($_POST[“ip”])) && (isset($_POST[“port”]))) { \/\/if a filled textbox was submitted $data = $_POST[“text1”]; $ip = $_POST[“ip”]; $port = $_POST[“port”]; $fp = fsockopen ($ip, $port, $errno, $errstr, 30); \/\/open the socket if (!$fp) { \/\/if the socket does not exist echo “$errstr ($errno)\\n”; } else { \/\/if the socket exists fputs ($fp, $data); \/\/ send the data down the hole to the other end echo “<font size=’2′ color=’navy’>Message Sent: ” .<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-54","post","type-post","status-publish","format-standard","hentry","category-PHP"],"_links":{"self":[{"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/posts\/54","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/comments?post=54"}],"version-history":[{"count":3,"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/posts\/54\/revisions"}],"predecessor-version":[{"id":814,"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/posts\/54\/revisions\/814"}],"wp:attachment":[{"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/media?parent=54"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/categories?post=54"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.tigoe.com\/pcomp\/code\/wp-json\/wp\/v2\/tags?post=54"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
