I'll give those a try when I get back to the site after the Great Pate
Ree Autic Holly Daze. I'll let you know how it goes... these devices
are pretty stoopid, so the handshaking et cetera is basically
meaningless - they're only receiving from around 6 or 7 characters
(The change machines) to maybe 40 (the customer displays), so there
really aren't any grave concerns... it just has to be the right speed
and format!

Thanks for the pointers!
