> fix, I recommend using xterm's vttest[3] to test the features. I have used vttest while I was coding in st, and it passes almost of the test for vt100 (vttest does test for features of xterm, vt2xx, vt3xx and even vt5xx). I could pass some test, please if your version of vttest report some error please notice me about it.
