28: * Based on the description by Paul Williams at:
29: *
30: * http://vt100.net/emu/dec_ansi_parser
31: *
32: * With the following changes:
33: *
34: * - 7-bit only.
35: *
36: * - Support for UTF-8.
37: *
38: * - OSC (but not APC) may be terminated by \007 as well as ST.
39: *
40: * - A state for APC similar to OSC. Some terminals appear to use this to set
41: * the title.
42: *
43: * - A state for the screen \033k...\033\\ sequence to rename a window. This is
44: * pretty stupid but not supporting it is more trouble than it is worth.
1.37 nicm 45: *
46: * - Special handling for ESC inside a DCS to allow arbitrary byte sequences to
1.77 nicm 47: * be passed to the underlying terminals.
