Minicom and the b l?

[Paul Migliorelli (+1 3 0 3 5 4 3 2 3 1 1)]

Hi all.  A while ago, I had successfully gotten minicom to transfer to and 
fro the brl lite 18

Allas, for some reason, transfers have stopped working, and I've totally 
spaced what I could have done to make it successful.  Any ideas what the 
settings should or could be on both?  That is, hardware or software 
handshake on this one, and what else on that one?  I'd think after all 
these years dealing with such things I'd remember some basics (grin).  
Thanks much as always.
