//
// This description suggests that if the first byte of parameter bytes is one of

// Example:
//
// In DEC VT-series, '?' prefix is commonly used by such as DEC specific private modes.
// "CSI > Ps c" is interpreted as the request of Secondary Device attributes(DA2).
// In some highter version of VT treats "CSI = Ps c" as the request of Tirnary Device attributes(DA3).
// The terminal emulator Tera Term and RLogin use '<'-prefixed extensions for IME support.
// "CSI < Ps t" means "change the IME open/close state".
