Yes, it IS a true V.32/V.42bis 9600 baud modem.  Where have you been over
the last year and a half while the V.32 protocol was being (rather loudly)
announced?

I had a PP 2400SA until two months ago, when I gave it to my dad for his
system, and since I needed FAX capability (for my business) as well as V.32/
V.42/V.42bis, I had replaced it with a Prometheus ProModem 9600M Plus, two
weeks before they introduced the Ultima :-(

At least there's an upgrade path, although slightly pricey ($199)...
