ftp ls command substitution

Hi,

I'm wondering if there's a big difference using FTP on HPUX & Linux ?

In HPUX (B.11.11), I'm able to use the following (??? substitution)
ftp> ls rep.*
200 PORT command successful.
150 Opening ASCII mode data connection for /usr/bin/ls.
-rw-rw-r-- 1 justme adm 101962 Jul 6 2010 rep.log
-rw-rw-r-- 1 justme adm 896 Jul 6 2010 rep.sh
226 Transfer complete.
ftp> ls rep.???
200 PORT command successful.
150 Opening ASCII mode data connection for /usr/bin/ls.
-rw-rw-r-- 1 justme adm 101962 Jul 6 2010 rep.log
226 Transfer complete.
ftp>
?Invalid command
ftp> ls rep.??
200 PORT command successful.
150 Opening ASCII mode data connection for /usr/bin/ls.
-rw-rw-r-- 1 justme adm 896 Jul 6 2010 rep.sh
226 Transfer complete.

In RedHat Linux, I'm not able to use the question mark (?) substitution. Are there any fix or is it a limitation ?

ftp> ls luci.*
227 Entering Passive Mode (127,0,0,1,212,62)
150 Here comes the directory listing.
-rw-r--r-- 1 0 0 63 Feb 08 2012 luci.txt
226 Directory send OK.
ftp> ls luci.???
227 Entering Passive Mode (127,0,0,1,39,247)
150 Here comes the directory listing.
226 Directory send OK.

Any advise would be helpful.

regards,
