how to set ange-ftp to epsv?

[Xah Lee <xahlee@gmail.com>]

when using ange-ftp, is there a way to set epsv to off?

basically, when connecting to the server in the command line using
ftp, i get this error:

[xah@xahg5][Tue Jan 13 09:37:40][~]
ftp joe@example.com
Connected to example.com.
220 FTP Server ready.
331 Password required for joe.

ftp> ls

500 Illegal EPRT command
200 PORT command successful

421 Service not available, remote server timed out. Connection closed
ftp>

a web search suggests to use “passive off” and or “epsv” commands.
The epsv command worked for me.

ftp joe@example.com

ftp> ls
227 Entering Passive Mode (68,75,114,108,156,180).
150 Opening ASCII mode data connection for file list
... [file listed]

However, i need to use it inside emacs to be able to dev on the site.
i don't see any customizable var about epsv (extended passive mode) in
ange-ftp's customize panel.

(yes i know about sftp... Not a option here...)

Thanks.
