- If the terminal has hardware tabs, the command to advance to the next
- tab stop can be given as <STRONG>ht</STRONG> (usually control I). A "back-tab" command
- which moves leftward to the preceding tab stop can be given as <STRONG>cbt</STRONG>. By
- convention, if the teletype modes indicate that tabs are being expanded
- by the computer rather than being sent to the terminal, programs should
- not use <STRONG>ht</STRONG> or <STRONG>cbt</STRONG> even if they are present, since the user may not have
- the tab stops properly set. If the terminal has hardware tabs which
- are initially set every <EM>n</EM> spaces when the terminal is powered up, the
- numeric parameter <STRONG>it</STRONG> is given, showing the number of spaces the tabs
- are set to. This is normally used by the <STRONG>tset</STRONG> command to determine
- whether to set the mode for hardware tab expansion, and whether to set
- the tab stops. If the terminal has tab stops that can be saved in non-
- volatile memory, the terminfo description can assume that they are
- properly set.

- Other capabilities include <STRONG>is1</STRONG>, <STRONG>is2</STRONG>, and <STRONG>is3</STRONG>, initialization strings
- for the terminal, <STRONG>iprog</STRONG>, the path name of a program to be run to ini-
- tialize the terminal, and <STRONG>if</STRONG>, the name of a file containing long ini-
- tialization strings. These strings are expected to set the terminal
- into modes consistent with the rest of the terminfo description. They
