306 DEC LA210 Control Commands

HTS	Horizontal Tab Set∗
ASCII:	HTS
Control:	not applicable
Decimal:	136
Hexadecimal:	88

Performs the same function as ESC H and ESC 1. Adds a horizontal tab at a column, but not at a physical position on the page. HTS is valid only if the upper data bytes have been enabled by selecting "8 Bit DEC" in the configuration menu and if the C1 control codes have been enabled using ESC SP 7.

HT	Horizontal Tab
ASCII:	HT
Control:	CTRL I
Decimal:	9
Hexadecimal:	09

Causes the active column to advance to the next horizontal tab position to the right of the current column. If there are no tabs to the right of the current column, the active column becomes the column after the right margin.

VTS	Vertical Tab Set*
ASCII:	VTS
Control:	not applicable
Decimal:	138
Hexadecimal:	8A

Adds a vertical tab at the current line. Vertical tabs are set at line numbers not at physical locations on the page. VTS is valid only if the upper data bytes have been enabled by selecting "8 Bit DEC" in the configuration menu and if the C1 control codes have been enabled using ESC SP 7.

∗Changing horizontal character pitch also changes the physical position of tab stops. These commands only set or clear the tabs. The Horizontal Tab control code, HT, causes the active column to advance to subsequent tab positions.

Selecting or cancelling font pitches, changing the print quality to draft or NLQ, or changing the print area also changes the physical position of the tabs.
