If it's truly mission critical (and if it is, it sounds like your mission is in real danger if you keep dropping bytes!), you could do worse than look at Connect:Direct from Sterling Software. It's the standard transmission software for bits of the core financial transaction world in the UK and with good reason.

Sure it's "only" a secure transmission and there's plenty of free alternatives, but this is one time when I would recommend paying out for the certainty you need... Others will no doubt disagree, but having used a variety of things for mission critical file transmission, C:D is a safe choice.

A well known phoenomenon

I know he asked for the flamefest, but that's a tad obvious is it not? ;-)

Just a thought, but why not read the link? It's all in there, in the Wiki. I've had success with both 6 and 9%, and others have had success with as low as 3%.

For me, an hour strong sunlight (I say strong, it's all relative: think February in Northern England) was preferable to overnight with a UV lamp... Not really surprising, I suppose.

Get the stuff, be appropriately careful with it, and have a go.

I *think* that it's not oxygenating at all: the chemistry is replacing oxygen that is bonded to a bromine (or bromide? dunno) compond with a hydrogen compound. Or something like that.

I think it's absolutely not oxidation: the "vanish oxy action" is used for its TAED content which may act as a catalyst, not the oxygenating properties.

quite possibly my favourite book, still... Although my username and URL probably give that away somewhat ;-)

Excellent writing with a definite style all of his own, accessible plot which you can take the clues of where it's going and feel all clever as a reader... Just a superb book, as are most of Banks' works. I'd also agree on avoiding excession as a device to break into Banks: the parent poster's thoughts echo my own.
