+Developing ESPTerm wasn't an easy task, because the information is scattered across many places and the existing 
+terminal emulators I originally used for reference (terminator, Konsole) are not implemented correctly in some details.

+A great tool for checking my implementation has proven to be [VTTTEST][vttest] and Xterm as a reference
+implementation that is probably the most complete emulator available, although it's cumbersome to use and its age

 I've comnpiled a list of those I found most helpful here: [VT100 emulation resources][resources]
