Re: [twsocket] SocketRcvBufSize for Listen sockets

Re: [twsocket] PCSensor server/ Simple client-server
Hi, to the target server, I need to send just two bytes, 0xBB and 0x83 You only need the HttpCli if you use HTTP protocol. Your device does not. It uses his own protocol (receiving 2 bytes - sending results). So you need to develop a simple TCP client program using TWSocket. If you need to send the first item after the device gives you some welcome data then you have to examine that in OnDataAvailable and send from there. If it does not you send the 2 bytes in the OnSessionConnected event. Just fire some more questions if you need it :) -- mvg, Wilfried http://www.mestdagh.biz http://www.comfortsoftware.be http://www.expertsoftware.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be

Re: [twsocket] PCSensor server/ Simple client-server
Not a WEB server, not a TELNET server, but still a server, if only a simple one. HttpTst, and the program I derived from it, as I understand things, sends a proper HTTP Get to the system of your choice. Your box is almost certainly both a web server (how you got and set configuration information) and a telnet server. Telnet simply means lines of data to and from the server, and is the basis of HTTP, FTP, SMTP and the rest. Those protocols simply use a different port to 'telnet' but the same textual interaction. Using HTTP components is totally wrong. If, using a telnet client, you don't get an open connection on port 5200, there is a deeper problem. You may be easier using standard applications, like my ComCap tool which uses ICS, it is designed for capturing data from devices such as yours, often hundreds at the same time, and will send a command to wake them up, as you need. http://www.magsys.co.uk/comcap/ Angus -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] PCSensor server/ Simple client-server
Angus, Wilfried... Many thanks! You need to develop a simple TCP client program using TWSocket... Thank you for pointing me at the right demo to work from Oh! And in looking around for that, I found the link Click here for a primer text about TCP... Apologies, everyone, for not seeing that before now. Would the demo Client5: A basic client program using TWSocket component. seem to you who know like an alternative good starting point for my efforts? Using HTTP components is totally wrong. Thank you... It is a relief to learn I don't need to fight that particular fight at this stage. What a newbie does NOT need to worry about is almost as helpful as what IS needed! Your box is almost certainly both a web server and a telnet server... Because that's how most things are made? This is a wonder out of China, remember. Not to argue with the experts, but just some of the tests I did that made me think, hmm... maybe not the usual here... Pointed my browser at 192.168.0.241:5200... got can't connect... and yet SmartSniff sees communication to and from there... across two sockets, if I use the mfg's software... which works... it just doesn't do the things I want to! ping 192.168.0.241 gets replies ping 192.168.0.241 5200 says could not find host on... Telnet... I can get into Telnet, but o 192.168.0.241 5200 fails, as does o 192.168.0.241 The first hangs the DOS window, the latter comes back promptly with Could not open connection... (I set the IP address, and got the config data with the mfg's software.) Telnet simply means lines of data to and from the server, and is the basis of HTTP, FTP, SMTP and the rest. Those protocols simply use a different port to 'telnet' but the same textual interaction. Helpful, thank you... I stuggle... but I learn! If, using a telnet client, you don't get an open connection on port 5200, there is a deeper problem. When I described my Telnet experiences, I was talking about using the bog standard DOS telnet command, inside a Windows command, or DOS window. Deeper problem... happily, the device DOES seem to work consistently under the mfg's software... I'll go away and study the latest advice, and dig into some stuff someone else has kindly sent off-list and hopefully announce SUCCESS... or at least come back with better(?) questions?? I am a lot more clear on the issues that I was when I started... thank you all for your help!

Re: [twsocket] PCSensor server/ Simple client-server
Hi, Would the demo Client5: A basic client program using TWSocket component. seem to you who know like an alternative good starting point for my efforts? The good starting point is: do not copy! - Study example; then start from nothing - zero - null ! -- mvg, Wilfried http://www.mestdagh.biz http://www.comfortsoftware.be http://www.expertsoftware.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] PCSensor server/ Simple client-server-SOLVED!
Hurrah! Thank you everyone! The ICS demo CliDemo1 did the job for me!! But I never would have got all the parts of the puzzle assembled without your help... There was a lot more to get right than just deciding which demo had the right elements. Now I can move forward with helping some good engineers working hard in a second language to get their product understood by a wider audience... thanks to you! (I still have lots to learn in this area, so, despite immediate wants (needs) having been met, if you still have comments on ignorance revealed in earlier posts, don't hesitate to put me straight.)
