I've been trying to download the ATR version of HiassofT's high speed SIO patch that I got off of his website: http://www.horus.com/~hias/atari/. When I write it out to an Atari floppy, there isn't anything on it, though some disk space is used. I've tried a few different versions of DOS, but no go. I'd like to use this with a stock 800XL to make an ultraspeed 800XL OS.
Something tells me I'm doing something inherently wrong here, as I haven't had any trouble using the SIO2PC dongle from Atarimax. I'm looking for this file or even this already in an Atari EPROM. If somebody can help me out or pass me the ROM OS file I would greatly appreciate it.
