Top Forums Shell Programming and Scripting POSIX way of getting columns in tty? Post 302275404 by Perderabo on Saturday 10th of January 2009 07:42:24 AM

I guess you have never used a tty. There is no standard way to obtain columns or rows. There are lots of situations still in existence where it cannot be done. Most true terminals never had a way to inform the host about parameters like that because columns were pretty much locked to 80. A real teletype can't even reasonably have a notion of rows. It can't back up to the "top", you might have ripped off the paper. And how far it can go down depends only on how much paper is left. Real teletypes always had exactly 80 columns though. The tty driver was designed for real teletypes. HP had a super printing terminal that could support up to 132 "columns", (but we used the term "print positions"). It used pin feed style paper. You varied the columns by changing the paper. But the host could not enquire about paper size. Posix does not require that stty know about columns.
