serial pass through Protocol

Hello
i creates a custom firmware and i would use replicatorg with serial pass through driver
but i not found the protocol
I only find the FirmwareResponseProtocol [reprap.org]
but i need more information

you know where I can find the protocol?

thanks

The closest there is to a protocol definition is here G-code For finer detail you need to look at the source code of your host and/or printer firmware.

I've put in a redirect, so this page now points directly to what bobc mentioned.

The truth is, the RepRap community simply refuses to define or respect anything which only vaguely looks like a standard. Developers do what they think is best at the time of writing the code and rarely look what others are doing. Newer slicers and hosts somewhat adapt to this model and allow to define different G-code flavours for each firmware.

So, to find out what the "protocol" is, you have to either try what other firmwares do, or to look into your hosts's source code to see what fits.
