Nice try, but this won't solve the problem. It's that AmigaDos asks SER:
for 256(? really a guess) characters at a time.

As before, I think it's more on the order of 256.

I will be posting an AmigaDos handler which allows just this. It takes care
of the most obvious LF -> CR,LF conversions, etc.
It will be posted in both executable and binary (uuencoded) forms. This is
(partly) because someone will probably want to hack it up to his own needs,
and (partly) because it might be of some educational value.
I have a few more modifications to make, one being a slight problem with
the skeleton handler Phillip Lindsay provided (thanks, Phil!), and I really
should comment the thing before posting. Hopefully in the next week or
so. It really is quite slick (thanks Amiga!).
