I'm curently working on my wall plotter, and have implemented basic G-code interpretation.
The problem is of course flow control via serial. Never ran into the problem until now, that's a HUGE design flaw.
So, G-Code is meant to be sent a line at a time, waiting for "ok", then sending next line and so forth... if this flow control isn't used, the data overruns the buffer, and you're all done.
Where the heck can I get a simple "terminal" program using this handshake? I've seen reference to a Processing app that's for just this purpose.. but I can't find the app anywhere. I don't want to download the entire RepRap host just to dump a text file with this simple handshaking, nor do I want to re-invent the wheel and require others to also... nor do I want to load Python, etc. I can do it in any one of several languages, but it seems awfully silly, as it must be a common task. I can't even find anything that works on the RepRap forums.. the closest, a command-line "gcode-sender" doesn't work with the COM ports the FTDI/USB sets up as. (in my case COM13)
Note that RealTerm will not run under Vista. I'm not sure why this is so, but I've never had a successful install under Vista.. even installed as admin. That's a real shame, it was a great program.
I know there HAS to be a terminal program or Vista-friendly utility out there for this.. whatcha guys using to get past this PITA?
