Fw: serial to ethernet converter

Fw: serial to ethernet converter

[Edgar]

Hy friends!

Scuse me boring you. I´ve joined this group just for ask you about this
question and I will leave as soon as I get some help. (or not)

I need some code, some idea, anything that help me to build a software based
gateway (C language) to connect serial devices on a Ethernet bus using a PC
whith Linux. Can someone help me?


Thank´s for your attention...

Well, there are several things that could be done, but you're a bit too
unspecific to really help you.

The most important question remaining is: how do you physically want to
connect serial (rs232 or something like that?!) to ethernet?

There are some realls small microcontrollers available doing this. Then,
you'll need the software port. There's an extension to the telnet
protocol that encapsulates serial data for (networked) devices. I think
this is the (software) way you should walk down. That'll increase
interoperability a lot...

RFC2217, that is...
