Ftp freezes on w32

[Lennart Borgman]

I have seen a problem with ftp on w32 which I have not had time to 
report before. The problem is that if I make a small pause for some 
minutes then ftp hangs. Looks like there perhaps is some problem with 
the ftp process. Here is a more detailed description:


I have downloaded the ftp program mentioned on 
http://www.emacswiki.org/cgi-bin/wiki/AngeFtp and my 
ange-ftp-ftp-program-name is c:/dl/ftp-for-win32/Release/ftp.exe. I am 
using w2k on this pc. My CVS Emacs is from 2006-11-03.

I open a remote file with the name 
"/ftp:address@hidden:/htdocs/somepath/index.html". After 
doing the first changes to the remote file point is on line 79 in the 
buffer "*ftp address@hidden".

Now I wait maybe 10 min. Then I try again to change the file. Now Emacs 
freezes right after the first character, but C-g helps and the screen 
gets updated again. Looking in the ftp buffer point is still on line 79 
right after the prompt. However now there is some text after the prompt:

 ftp> quote mdtm /htdocs/somepath/index.html

If I in the window showing the ftp buffer now press up arrow I get the 
error message:

 Wrong type argument: processp, nil

Now I try again changing the file. It succeeds and there are about 30 
new lines in the "*ftp someuser@ ..." buffer. Here is the content from 
from some lines above 79 to the end:
