I have been searching with google trying to find information with examples that contain the exact bytesequence what is send over the serial intrface to the GRBL-software.
"The host PC interface simply sends a line of G-code to Grbl"
Well developpers how about adding a few examples how those lines of G-Code look like!
Can I really send any line of G-Code to GRBL and GRBL will understand it? I highly doubt that.
This means GRBL understands only a subset of possible G-Codes.
It would help a lt for developing a interface if you would provide a few examples right at that place of the documentaion
Attempt to precisely describing what I mean:
What I mean is:
imagine a computer that is running for example "universal-g-code-sender" and send data to an arduino running the GRBL-firmware:
if you would connect a "sniffer"-interface on the Tx-Line (which sends the data from Computer-running-universal-gcode-sender)
and a second "sniffer"-interface to the Rx-line (where the Arduino running GRBL-firmware sends back responses to universal-G-code-sender)
What bytesequence will be printed in the sniffing-software?
Sure this depends on the g-code that will be transferred but a few examples should give a pretty good overview about the pattern that GRBL expects.
This would answer questions like:
Does the GRBL-software need a leading "<" and a trailing ">" as the start-/ endmarker?
Does there have to be a space between XXZ-coordinates?
I know this is not an GRBL--firmwareissue, but it is a documentation-issue
So please post a link that guides me to such examples

I have read this documentation: https://github.com/gnea/grbl/blob/master/doc/markdown/interface.md it does explain a lot but the only thing it says about a typical bytesequence sended to GRBL is
"The host PC interface simply sends a line of G-code to Grbl"
