Telnet Client & Wiznet

dcole

Hello,

Is there any telnet clients written for the Propeller that would work in combination with a Wiznet module to directly connect to the Internet and telnet to a remote computer?

Thanks,

David Cole

I have always wondered if it was possible to build something like this. I would be awesome to telnet into a BBS with a propeller.

Sound like... http://hackaday.com/2009/02/25/propirc-propeller-based-irc-client/

I'll take a look at that JDat.

I have seen many pages about using the prop as a serial terminal and then connecting through the Internet that way but I would like to know if there is existing projects for telnet programs.

Another theoretical solution: http://obex.parallax.com/object/602
But...
1) Ehternet phy on ENC28J60.
2) TCP/IP stack on propeller.
3) Something broken (not compiling for me).

Hi David,
Peters Tachyon-Forth system includes a TELNET SERVER.
so your question made me curious about his implementation.

In gooogling around I found this:
ftp://ftp.rfc-editor.org/in-notes/rfc318.txt

and in there:

MINIMUM TELNET IMPLEMENTATION

Using Site:

1) User must be able to enter and transmit all ASCII codes.
2) Ignore and delete all Telnet signals from the serving site.
3) Provide local echo for local user terminals.
4) Implements CR LF end-of-line convention.
5) Provide for the User Telnet signals.


RFC 318 Telnet Protocol April 1972


Serving Site:

1) Provide a mapping between ASCII and the local character set.
2) Ignore and Delete all Telnet signals from the using site.
3) Assume the using site provides echoing.
4) Implements the CR LF end-of-line convention.

so if you have a socket level connection, not much more is needed.

Peters Telnet server implementation atm. is about this - minus 2).

AND IT WORKS ;-)

you can telnet to the SPINNERET or a Prop with W5100 / W5200 / W5500
and there you have the interactive TACHYON Forth prompt.

Thanks for the info. I think I am getting confident enough to play around with this.

I have found the WIZ110SR which is a serial to ethernet converter. It handles the TCP stack and makes the connection to the remote server for you. The propeller would then just need to handle the serial coms side of it in a manner that is sufficient for the telnet server on the other end to talk with it. I would probably use Briel's PockeTerm device for the propeller side.
