We bumped into the same problem when we took the ordinal(char) approach. A small hiccup on the line easily makes an A an E
The bit by bit approach we use
(http://www.sensepost.com/research/squeeza/) makes this problem much easier to deal with.. i.e. we once had an insanely bad connection to a box and upp'ed the delay per bit to 14 seconds.. i.e, 14 secs == 1, 0 == 0. The analyst aged a few years while waiting for the output he needed, but you can be fairly confident of the integrity of the data.
(its why squeeza happlily does a transfer of binary files from the server using just timing (and patience))
Ps.. checkout the paper on the same page for snippets of the sql we are using.. -- Haroon Meer, SensePost Information Security | http://www.sensepost.com/blog/ PGP: http://www.sensepost.com/pgp/haroon.txt | Tel: +27 83786 6637
