Each page, but only the first inch?  Yeah, this sounds like flow
control all right... assuming there actually is imaged data on the
whole page (HylaFAx will chop whitespace).

I doubt it.

Well, first, I recommend against living without faxgetty; it's *much*
easier to keep track of things with it, and it don't take much
memory...

It seems to me I remember something about "\021" for the trigger,
instead of 022, but I don't remember why I think that.

Search the mailing list archive (at www.hylafax.org) for "flow
trigger" and see what you get.
