You could make a program which does what "resize" does to find the screensize: it moves the cursor and asks where it is.

The control sequence that does the asking is the cursor position report (CPR). http://invisible-island.net/xterm/ctlseqs/ctlseqs.html (also vt100.net). Not all terminals implement this (for instance FreeBSD console probably does not). -- Thomas E.

changing tab stops
I have a C program that writes to a terminal (currently xterm, but could be anything). For reasons I won't go into, I would like to read and change the terminal's tab stops ... from within the program ... in a generic/portable way. Is this possible? If so, what are the keywords associated with my first clue?

Re: Tab Stops
Matthew, Thanks for the reply. Since posting this message I have discovered a 'set ts=4' option in vi and a -x4 in more. I have also discovered that the tab stops are hardwired at 8 columns in kern/tty.c therefore cat can only ever use 8 column tabs unless tty.c is changed. vi was the main area where I wanted the 4 tab spacing. Again thanks for you assistance.

Tab Stops
I have a situation where I would like to reduce the tab stops from 8 character columns to 4 character columns. Any help on how to achieve this would be most welcome. Thanks in advance.
