I'm still fighthing with Xemacs on my laptop.
The conditions were as follows:
computer IBM Thinkpad 1161
init.el from Dr. Fox (28 Dec 2003, Ver. 0.5.4, I will send it if necessary)
and I always get the error message
<Timeout waiting for prompt. Check inferior-ess-prompt or ess-loop-timeout.>
I've read some old posts on the matter and
Rich Heiberger underlined that:

So I started playing with the section
>(setq win1 (selected-window)) ; win1 is on top
>(setq win2 (split-window)) ; win2 is on the bottom
>(R) ; start R in win2 -- assumes that the R bin directory is on the path
>(if dedicated-R-window (set-window-dedicated-p win2 t)) ; window win2
dedicated to R process
>(select-window win1) ; back to win1
>(R-mode) ; put *scratch* buffer in R mode
>(balance-windows) ; equalize size of windows
of the init.el file, using the -q option, C-x C-e and M-x eval.region
trying to get the cursor in the right place, but without success.
Sometimes I was able to get things going, but I was not able to reproduce
Eventually I was frustrated a bit and decide to change ess and R
ess 5.2.1 to 5.2.2
R 1.7.1 to 1.8.1
and adding the line
init .el file
changing the path to R and modifying the path in the autoexec.
Using the -q option, M-x eval.region in the init.el up to line
<;; and the R process at the bottom>
and submitting each line after,
I noticed that R starts in the upper window (win1) instead that in the lower
Playing with cursor position and line submission
I finally came to some changes in init.el,
eliminating the two lines as follows
;(select-window win1) ; back to win1
;(R-mode) ; put *scratch* buffer in R mode
Everything seems to go well, I can get the Dr Fox's icons and all,
except that I get only a R window. To correct this I therefore move to
send ls() and then C-x-o (or 0 do not have the manual handy)
and start my R session with the scratch buffer above and R buffer under.
Unfortunately I do not have the two items under the pull down menu
"just quit" and "quit saving R workspace".
To quit neatly I have to delete all buffers and finally exit Xemacs.
As you imagine is not practical to work like that so
what should I change in the init.el,
in order to have things going straightier?
