I think that I've found a bug in this program. On my Pentiums,
both a 133 and a 166, when doing a block of 2^28 keys, the program
dials in after only 50% of the keys have been searched, about 400
seconds before the block is done. With a block of 2^30, it dials
in after only 13% is complete.

I puzzled over this for a while, and then noticed that at both of these
points occured at the end of a line of .'s Could there be a bug in
the end of line dectection? Or at the very least, detecting when to

If I hang up after it dials in by mistake, it'll try to reconnect at the
end of the next line.

Anyone else nothice these "features" ?

Also, I don't think that this GUI handles a busy signal, or a failed
very well.
