I now have Internet Chat mode enabled on my SB70LC

Post by Kiwinet »

This is a chat text alternative to Skype done via an NB SB70LC Ethernet to Serial module :lol:

Acknowledgements and credits go to the NetBurner Software engineers:-
80% of the code is directly from NB's TCP to Serial example in the C:\nburn\examples\serial\tcp2serial directory to enable Telnet on Port 23.
Approx. 20% of the remaining code is from NB's MOD5270 Flash webserver example to activate the "Keep Alive" heartbeat connection on port 10 000. This is shown on http://microwebserver.net/index2.htm but it is still in development during my busy weekends to eventually activate and monitor temperature controller(s) via the RS232 ports.

See http://microwebserver.net/chat.htm for user instructions.

N.B. Chatmode does work fine but there are a couple of drawbacks at this stage of the game.

1.- there is no audio ring to alert me when someone else has made a connection onto Telnet
2.- Can only chat just to one person at a time.

I am using either MTTY or Windows Hyperterminal for chatting via the RS232 serial port during Australian time! ;)

Cheers

Yes, it is interesting how things do pan out. I originally purchased the SB70LC module a just few months ago, with the intention of making it send a cellphone text message on receipt of an alarm condition via the Internet.
The only catch is that it requires HTTPS or SSL (Secure Sockets Layer) encryption to make this kind of application work via a UDP Port 5060 SIP netphone server . The SB70LC has SSL software already preloaded from the factory with it for direct RS232 or RS485 Serial to Ethernet data conversion, but if you want to customize it for other additional secondary tasks you need to pay $500 USD licencing fee for use in your manufactured product.
OK for some, but not for your average hobbyist like me.
Afterwards I soon found other ideas which I could put the SB70LC to good use without having to go down that SSL data path.
The idea of hosting your own WebServer without paying ISPs to host your webpages is very appealing - up to 8GB of stored data (via a cheap digital camera FLASH memory stick that you can slot into the SB70LC module). Enough to run quite a few movies through an Adobe FLASH webplayer. :lol:
