Set Presentation Highlight (SPH) (ESC [ @)

SPH activates or deactivates double wide, double high, and italic printing. This
command is supported in Native 4247, 4202 III XL, and 2381 emulation with some
exceptions, as noted.
Once these highlights are active, they remain active until terminated, either by
another SPH command or an initialization. If double wide printing is activated by an
SPH, a DC4 control also can cancel it.
A two-byte count (LL HH) indicates the number of bytes that follow in this control.
LL is X'00' to X'04'. HH is always X'00'. If the count equals X'0000', the control is
ignored.
