Re: TCP Messages to Server
Not possible on a shared web hosting service as I doubt they'll permit you to run any sort of service and may be locked down a lot further depending on how switched on the provider is. VPS will do it no dramas. You'll need to write some sort of service to bind to an external IP and port. Piece of piss and heaps of code around to start from. David.

You probably could if you use assumed port 80and got your modem to send a simulated page get with the headers From: ozdotnet-boun...@ozdotnet.com [mailto:ozdotnet-boun...@ozdotnet.com] On Behalf Of David Connors Sent: Tuesday, 10 September 2013 6:31 PM To: ozDotNet Subject: Re: TCP Messages to Server Not possible on a shared web hosting service as I doubt they'll permit you to run any sort of service and may be locked down a lot further depending on how switched on the provider is.

RE: TCP Messages to Server
Actually if I could turn it into a http request with a query string that would make the web code simple. Is it just a matter of having http headers? The modem data does attached to a web site. Hosting terms seem to allow a service as long as it integral to the site, which it is.

Yes it is..use firebug or jsfiddler to get a standard template(with headers) you could use.

RE: TCP Messages to Server
Anthony / David, Thanks, seems to work well on shared hosting using port 80. The following seems to be the minimum construct for a raw TCP message to become a HTTP request - Message = GET /default.aspx?Msg=ddrrggffdd HTTP/1.1 vbCrLf Host: www.mugachino.com vbCrLf vbCrLf The server returned the following - HTTP/1.1 200 OK Cache-Control: private Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.0 X-AspNet-Version: 4.0.30319 X-Powered-By: ASP.NET Date: Wed, 11 Sep 2013 05:24:15 GMT Content-Length: 1338 Strangely the HTML section did not come through in the NetworkStream ?? My objective is achieved (I don’t need the reply and only want to pass the query string) but it would be good to know what happened to the html portion.
