There are many solutions. You don't provide much informatiuon about your workign environment so it is difficult to make a good recommen- dation. Standard solutions include: use a modem to attach to the serial console; use a terminal server to attach to the serial console; etc.

Use of a modem or a terminal server to attach to the serial console is not a good solution for me, because I hope to deploy at least several hundred of instruments. And the only link I have with them is thru Ethernet. That's why I'm looking for something similar as telnet.

Thanks for your reply,

Laurent
