I've been listening in on this newsgroup since I received my new Cardinal
14.4k v.32bis fax-modem.  It seems that many people here bash the Rockwell
ASIC chipset.  I am not a proclaimed modem expert, but the experience
I have had thus far with this modem has been excellent.  Using the 
specific commands Cardinal specified in their manual has resulted in perfect
operation.  I am able to connect with 1200baud - 14,400 baud modems with
one initialization string.
 
Furthermore, the included, (although extremely buggy) QuickLink II Fax
software could be excellent if some changes were made (I'm speaking of the
Windows version)  All of the FAXes I've recieved were at 9600 baud.
I haven't had any slower ones yet.  The windows software can automatically
differentiate between data and FAX calls.  
 
This modem does have a NS16550AFN UART, and is so reported by MSD and other
verification tools.  On this 486/33, I routinely get ~1700 cps connections
to other v.32bis [TwinCom modems on EXEC-PC], sending ZIP files with v.42bis
error correction.  I can multi-task in Microsoft Windows -- play CPU 
intensive MOD files, write documents in Microsoft Word, and download using
QMODEM 4.2F using YMODEM-G, simutaneously.  
 
Connections to USR modems are somewhat slower, but only about 50 cps.  I
have not been able to definitively compare this with line quality, however,
so I'm not sure if the USR modem is the problem.
 
Connections to v.32 modems are flawless as well, connecting here at the 
univeristy consistenly at v.42bis.  The 2400baud and 1200baud lines connect
at their respective rates just fine.  With long distance calls, I have 
NEVER experienced a data carrier lower than 14.4k when dialing a 14.4k
system.  Granted, I have tried only a few systems, some using Zoom,
USR, and PPI modems.
 
In all, I am very pleased with this modem.  I was not particularly pleased
with the SERVICE that Zeos Int'l gave me, when I ordered it, but that
didn't surprise me.  Zeos sold this modem at $195, internal only.  You 
can't really beat that.
 
Here's the informations in my registers, and firmware versions:

When I started fooling with the registers and other commands, I got into 
trouble and the modem wouldn't connect in cases < 14.4kb.  However, when
I re-entered the suggested init code, all returned to normal.  I'm really
pleased with this modem, and pleased with the Rockwell Int'l chipset
that drives its faaaassssttt speed and loooowww price, with nnnnooo problems.
