How hard would it be to connect to EhBasic via ssh/putty(using the mentioned module)?

ssh is hard! Even telnet involves a bit of startup negotiation. But putty can connect using 'Raw' (as can netcat) so that would be dead simple - just like a uart.

What do you suggest, should i give it a try with this module?

if you're OK with the possibility that it can't be done, yes! Say it's 80%-90% likely that it should work.

I've found a cheaper module, but i can't find what is the difference between the two(the previous one and this): (datasheet)http://www.megaupload.com/?d=U1LCW40H
Only RS232 version?

The thing is, the 8-page documentation makes it very much a puzzle. You might have something wonderful, or might have a brick. This one, unlike the other one, mentions a web mode and mentions PPPoE. If it works, that might make it more sophisticated. It hints that it can also be used in a simple way - but it isn't at all clear. You must be prepared to lose the money, and to lose a weekend on it. Could be great, could be a dud.

Could you post a link to the sales site?

It is on ebay, but there is not much more info available, i might ask the seller to get some more info if possible.

Ok, same picture seen here

altho the price is higher.

I ordered the module from ebay, now i just have to wait for it for a month. When it comes, i plan to connect it with a usb to ttl serial module i bought previously. By doing that i could test the module and find out what it can do using only my pc. When i figure it out then i can connect it with my sbc, and start writing code... Is there any good program with which i can send data packets, and other kind of stuff so that i can test the module?

I think these modules come with test programs (for Windows)

Then there's putty in raw mode (Windows), and netcat (any platform)

You might want to use tcpdump or tethereal (linux) or Network Monitor (Windows) to see what packets are on the wire.

Should be interesting.

This may be slightly off-topic, but....
FPGACircuit ("domain name expired on Jan 11 2012" hahahaha) used to sell Spartacus FPGA board + Ethernet daughterboard. The demo design was 6502 (yes !) and uIP (or LWIP) serving a simple web page.

I finally got the module. I managed to get it working in udp mode, but i am having trouble with tpc, putty keeps crashing when i set to raw, and the program that i got with it won't connect to it via tpc either. What could i be doing wrong?

Edit: I got Java talking to the module in udp mode.

Which one did you get - could you point at, or attach, the documentation?

Putty really shouldn't crash, under any circumstance. You should have a look at this process.

If you take a packet capture using one of the tools I mentioned earlier, I can cast an eye over it.

Here is the manual.
How is a tpc connection established in general?

Have a look at this doc or similar ones. See attached picture of a packet capture of the start of a successful connection. I used microsoft's network monitor but I've also used wireshark in the past.

Thanks for the PDF doc - so the part you have is ETH2232X from hiersun-wintech, it does DHCP and PPPoE. (I see pdf attachment is not allowed)
