Page B-35APPENDIX B — SCS/DCA COMMAND SUMMARY
Command: Set Text Orientation (STO)
Format: 2B D3 nn F6 caca lala
Printers: 3812
Action: This command is used to specify character and line
rotation for subsequent text.
The caca parameter specifies character rotation angle
and is not supported on the 3812.
The lala parameter specifies the text line rotation angle.
Valid values are: 0000h (normal portrait), 2D00h
(landscape left), 5A00h (upside-down portrait), 8700h
(landscape right), FFFEh (Computer Output Reduction)
and FFFFh (default orientation based upon page size).
IBMEMUL: Same as the 3812.
The OPTIMA performs orientation selection in the same
way as the IBM 3812, with two exceptions. The
OPTIMA allows system-specified orientation with the
STO command to be overridden at the front panel option
FMTINFO: ROTATE=.
The 3812 does not allow the automatic orientation
selection of COR if the pq (print quality) parameter in
the Page Presentation Media (PPM) command is set to
01h (data processing quality). The OPTIMA does not
enforce this limitation.
One of the two PFSs, PORT> or LAND>, is sent to the
target printer at the beginning of each page. The LAND>
PFS is sent for either landscape or COR orientation.
275EMUL: No operation.
