Sidebar: A Useful Application Control String

Not connected to any capabilities, but handy for application programmers, is the following xterm control string: \E]P1;P2^G. (Note the inverted ] bracket. The ^G at the end is a literal bell 0x07.) P1 (a number) and P2 (a string) are to be selected from the following set:

P1 is 2	P2 is a new window title
P1 is 1	P2 is a new icon name
P1 is 0	P2 is both a new icon name and new window title
P1 is 46	P2 (re)defines the name of the logging file
P1 is 50	P2 defines a new font
