vi page setup
Hi All,

I am facing some strange problem. can anyone help to resolve this.

When i open any programs, scripts or any files in VI editor, only first 8 lines are displaying in the bottom of the screen. If i press control + f to go to next page, again second 8 lines are displaying.

I have to use down arrow key to display 24 lines in my screen. Again if i go to any line number, For Example :se 2014
again 8 lines are displaying in my screen from line number 2014.


terminal details :

TERM=vt100
TERM_DEFAULT=lft
TMOUT=1800

Any specific setup has to be changed ?

My OS is : AIX

Do you have the file .exrc in your home directory? Thay has controls over what vi does and how it behaves. There is also the following snippet from the man page for vi:-
Quote:
window (wi=) Sets the number of lines displayed in one window of text. The
default depends on the baud rate at which you are operating: 600 baud or less, 8
lines; 1200 baud, 16 lines; higher speeds, full screen minus 1 line.
It is also possible that you have a short terminal defined somehow, perhaps.
Another snippet is the setting for z:-
Quote:
zNumber Makes the window the specified number of lines long.
.... again probably in ~/.exrc


I'm not sure if this helps, but maybe......

Anyone else?

Hi Robin,

You are exactly correct. My terminal baud rate is 300. i executed stty command and found it.

speed 300 baud; -parity
eol2 = <undef>; dsusp = ^Z; lnext = <undef>
brkint -inpck icrnl ixoff onlcr tab3
echo echoe echok

I changed into 2400. Now i am getting 24 lines in a screen...Gr8 and thanks for your help.

By the way, is there any impact because of changing baud rate?

Not that I'm aware of on non-archaic network kit, unless you have a very convoluted route across multiple networks and the throughput is terrible, e.g. a remote branch operating over a 500K dial-up (if you can still get those?)

Anything that is reasonably good should be fine. I even used to have a 28k dial up from home for remote suppose that would work just fine. It is only your personal experience of having a problem that would illustrate an issue. Perhaps the odd missed keystroke or unprintable character, especially when using cat on a large text file. That could flood it out, but otherwise, i would not worry too much. It's nothing that you can't undo really.



Glad to be of help.

Robin
