ESC B
Sets vertical tab stops (IBM/EPSON).
ASCII Code ESC B n1 ... nx 0
Hexadecimal Value X'1B' X'42' n1 ... nx 0
Decimal Value 27 66 n1 ... nx 0
Range 1 = n = 255
In EPSON mode, it sets the vertical tab stops in the 0 Vertical Format Unit (VFU) channel. This code sets
up to 16 vertical tab stops at the line specified by n1, n2 and so on in the 0 VFU channel. The tab stops
are memorized as physical positions. In IBM mode, this code sets up to 64 vertical tab stops at the line
number specified by n1, n2 and so on in the 0 VFU channel. The tab stops are retained as logical
positions.
ESC B NUL
Resets vertical tab stops (IBM/EPSON).
ASCII Code ESC B NUL
Hexadecimal Value X'1B' X'42' 00
Decimal Value 27 66 00
This command resets the vertical tab stops in the 0 Vertical Format Unit (VFU) channel.
ESC b
Sets vertical tab stops in one of the 8 Vertical Format Unit channels available. (EPSON)
ASCII Code ESC b mn1 ... nx 0
Hexadecimal Value X'1B' X'62' mn1 ... nx 00
Decimal Value 27 98 mn1 ... nx 0
Range 0 = m = 7
1 = n1 ... nx = 255
This sequence sets vertical tabulations in the VFU channel specified by the parameter m.
The VFU channel can be imagined as a blank page where you can set up to 16 vertical tabulations in
order to format your page as you like. 8 channels are available and in each of them you can create a
sample page that you can recall later. n1 to n16 specify the lines at which vertical tabulations must be set.
The values of n must be in ascending order. If you change the vertical spacing, the vertical tabulations set
are not cancelled and they maintain their physical position on the page.
The vertical tabulations set in the channel specified by the m parameter are executed by the VT code
when the specific channel is selected by the ESC / command, this code is executed as a line feed.
