Subject: problem using ange-ftp to access files on QNX4 machine
Date: Tue, 20 Jan 2009 14:07:40 -0500 (EST)

Attempting to access files on a machine running QNX 4.25 using ange-ftp from
Emacs 22.1.1 on FreeBSD fail, as illustrated by the following contents of
the ftp buffer after attempting to fetch a remote file "/wbp <at> maple:.emacs":

Possible patch:

Changing line 732 in ange-ftp.el as follows:

732c732
<         "^22[789] .*[Pp]assive\\|^200 EPRT\\|^500 .*EPRT")
---
>         "^22[789] .*[Pp]assive\\|^200 EPRT\\|^500 .*EPRT\\|^500 .*EPSV")

I'm not sure if the above is the whole answer, however, since there is
still a warning:

  Warning! Unable to get home directory
