I posted quite a few pages, there's more to do, but you will get the
idea. It's on www.tech-diy.com
you can play around with the codes, create a "*.txt" file and send it
with the following commands:
mode com1:9600,n,8,1,p
copy myfile.txt com1
I use WordPad instead of NotePad, as WordPad has "find and replace".
I've taken apart some of the Gerber files generated by Ultiboard --
they can be quite simplified -- the most annoying and time consuming
is the AA -- arc absolute -- in Ultiboard a 1% angle is specified --
this can and should be changed using "find and replace" in Wordpad.
