31: * Based on the description by Paul Williams at:
32: *
33: * http://vt100.net/emu/dec_ansi_parser
34: *
35: * With the following changes:
36: *
37: * - 7-bit only.
38: *
39: * - Support for UTF-8.
40: *
41: * - OSC (but not APC) may be terminated by \007 as well as ST.
42: *
43: * - A state for APC similar to OSC. Some terminals appear to use this to set
44: * the title.
45: *
46: * - A state for the screen \033k...\033\\ sequence to rename a window. This is
47: * pretty stupid but not supporting it is more trouble than it is worth.
1.37 nicm 48: *
49: * - Special handling for ESC inside a DCS to allow arbitrary byte sequences to
1.77 nicm 50: * be passed to the underlying terminals.
