RE: [Jmodbus-devel] List and comments

Dieter,

That stability sounds great.

I have also seen fantastic stability from by original, non-hardened
implementation that sits on the TINI's I have here at work.  The TINI's now
have up times of 84 days and the slave processes have been running for all
of that time.  Every few days I startup Citect to connect to both of them
and just see it is still working.  I'm not sure how many requests this would
have handled but it would be many hundreds of thousands.

It's a nice thing about the Modbus protocol in that the way the protocol is
written there are enough checks in there that you always really know what is
happening, thus giving you a fighting chance of creating a solid, fault
tolerant implementation.

If you would either be able to send me a tarball of the code you are working
on, or a link to it before the weekend that would be great.  I'll probably
spend most of tonight working through your code and making sure I know how
it works before I start to merge the two together over the weekend.

Cheers,

Kelvin
