The problem with retries should be fixed in 4.5.2.

You can also try this patch for 4.5.2 which adds "ftp:site" setting for
tuning the connection after login. For your case it would be

   set ftp:site "SBD=(IBM-278,ISO8859-1)  LRECL=240  RECFM=FB"

(note the double spaces).

[Alexander V. Lukyanov]

lftp-4.5.2 has been released. Changes:

* fixed a coredump on startup when compiled with certain gcc versions.
* mkdir -q option for quiet operation.
* glob --exist and --not-exist options.
* improved torrent status, show piece availability statistics.
* remove unconnectable torrent peers on trackerless torrents.

Get it from http://lftp.yar.ru/get.html or your favorite mirror.
Binaries for Fedora 19 are also available.
