ASCII Code ESC b c n1 n2 n3 ... nk 0
HEX Code 1B 62 c n1 n2 n3 ... nk 00
Purpose Assigns vertical tabs to channels established by ESC /.
where c = 0 through 7
nx = 0 through 255
Comment Channels are selected by ESC /. The most significant bit of all the n
values is cleared when read, so that hex 81 becomes hex 1, and hex
80 becomes hex 0 which ends the load. The distance of each tab stop
from TOF is the current line spacing times the number of lines given
in n.
If paper movement is commanded to a value of n greater than the
page length, the paper movement command is ignored. The values of
n must be ascending order. If they are not, the sequence up to and
including the out of sequence number is ignored. The rest of the load
is processed. Skip over perforation is ignored.
You can clear any channel by sending ESC b c 0, where c is the
channel number.
