I am responding to this article using a 9600SA at 2400/MNP4. I have
gotten it working fairly well. I'm able to talk at 1200 as well. I'm
still working on faster connections.

I'm getting a news feed using the 9600SA at 2400/MNP4 and so far
am having no problems. I'll post an opinion about this modem after a
week or two of steady operation. I'll also send the settings/modes
once I get everythig going.

Me either...yet! The modem is going into service full-time at 1200,
2400, 2400/MNP4 as I type, faster speeds later.
