you might try rlwrap http://utopia.knoware.nl/~hlub/rlwrap/
I've tried it in the past, but ran into a couple of issues using vim on linux when editing from sqlplus.
Most of the issues were cleared up in 0.23. 0.24 may work better.
I don't recall just what the issue was, but it was fairly minor, and had to do with the way I configure vim.

In windows, at the sqlplus command prompt you can hit the UP Arrow key to get previous commands. How can I do the same in Linux?
