Dear Community - I'm thinking of having a Ethernet communication "bridge" over a much slower serial line. My questions are:
- Does anybody built it already? Hopefully with schematics etc. Lniks on the Net?
- Exists time-out values in the Ethernet spec? If I have a slow link there maybe several hundred milliseconds before the answer comes back. Overflow possible?
- I think of using a W3100A or Realtek Ethernet Controller along with a AVR. Is it possible to use a generic Ethernet Controller?
- I don't know if the circuit would be a Router, Bridge, Rub, Switch, Gateway in the Ethernet sense. What is the simplest answer?
- Would it be possible to make the circuit entirely protocol "transparent" (other than the long delay)?
- Anyone interested to share infos/project? BTW: I'm a electronics design engineer and don't want infos about commercial products. Regards - Henry
