(well, there's a set of patches for the ppp ethernet/serial device drivers, but I reckon you aren't using them - hardly anybody does).

(look at the respective file modification times first, but you can also use "version c:ftp full" and "version libs:bsdsocket.library file full").
It is not at all obvious what version of bsdsocket.library etc that belong to what version of Roadshow - it would be nice if all files, in addition to their own revisions numbers, could have "version full" strings that say something about version of Roadshow they belong to.
