Specifications

Simple TTY Emulation
Horizontal Tabs
Default horizontal tab stops are set at every eighth column, i.e. column 8, 16, 24, 32,
40, etc. (The first column is column zero.) The default tab stops are associated with
columns, not absolute physical positions. Changing character spacing will change the
physical position of the default tab stops.
Horizontal Tab HT
Advances to the next horizontal tab stop. If no tab stop exists between the active
column and the right margin, the HT will be ignored. Default tab stops are set at
every eighth column, i.e. column 8, 16, 24, 32, 40, etc.
Control code: HT
Hexadecimal: 09
Vertical Tabs
Vertical Tab VT
Causes the current line to be printed, and then advances the paper to the next vertical
tab stop. If no vertical tab stops are set, then a line feed is done instead. If "Auto CR:
On" is selected in the "Setup: INTERFACE" menu, a carriage return will also be
performed.
It is not possible to set vertical tab stops in TTY emulation. If tab stops were
previously set in some other emulation, they will be used.
Control code: VT
Hexadecimal: 0B
Printer Controls
