There is https from Digi. If you are looking for a command prompt SSH, I developed one. It took three months of sleepless nights, but it works. I have also have had to rewrite telnet, ssl, tftp, sntp, hostname, DNS, and several other protocols for the ME.
The lesson learned from this is: If you want custom stuff, redo it yourself. Since you are in Chile, I cannot sell you my code since it has encryption, but if you have any questions feel free to ask.
