Unisys T27 Settings 201
SO/SI XTN
SO/SI XLT
Factory default: Unchecked
The setting of these options determine the effect of the ESC SO and
ESC SI sequences when receiving or transmitting data.
When receiving from the host, the setting of the SO/SI XTN option
determines whether the sequences are used to switch between stan-
dard and extended character sets (checked), or reverse highlight and
underline (unchecked).
When transmitting to the host, the setting of both options determine
the sequences used for switching between standard and extended
character sets, and reverse highlight and underline as follows:
XTN XLT SO SI Extended Characters
Reverse Video Underline
Sent as Sent as Begin End
OFF OFF SO SI ESC SO ESC SI
ON OFF ESC’. ESC’/ SO SI
OFF ON ESC’. ESC’/ ESC SO ESC SI
ON ON ESC’. ESC’/ SO SI
The SO (shift out) and SI (shift in) sequences allow switching
between two sets of characters: the standard character set and the
extended character set. Each set consists of 128 characters. When an
ESC SO sequence is received from the host, the emulation displays
all subsequent characters from the extended character set until an
ESC SI sequence is received to switch back to the normal character
set.
The Unisys T27 emulation transmits an ESC SO sequence when it
encounters extended characters in its display buffer and an ESC SI
when standard characters are to be sent. There is no automatic shift
in (
ESC SI ) at the end of a data transmission block.
