Bit 2 (ESC) is a read/write bit that is functionally
equivalent to the ESC pin in the serial mode. The
operation of this bit, like the ESC pin, is enabled by
setting U70[15] (HES) = 1
Bit 1 (RTS) is a read/write bit that functions in the
parallel mode like the RTS pin (Si2493/57/34/15/04,
pin 8) in the serial mode.

The operation of RTS and CTS is analogous to that in
the serial mode and must be enabled with AT\Q3. Bit 0
(CTS) is a read-only bit that functions in the parallel
mode like the CTS pin (Si2493/57/34/15/04, pin 11) in
the serial mode.
