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