I do not talk about "generally acceptable" and "casual use patterns". If I
recommend a modem, this means something like:

 put 500 faxes into a fax queue
 put a sending modem and a receiving modem on a local PABX
 send the faxes
 count the transmission errors

-- sending from an USR Courier to a ZyXEL 1496, I have sent over 900 pages
of fax during one day (just to see whether it is *really* solid), and *NOT
A SINGLE PAGE* failed. This is what I want to see in a modem.


If I recommend a modem, this means also something like my ZyXEL 1496
modems here. I think the last time I have switched them off was about 4
months ago, and the only reason why I had to do this was because I had 
some work to do on the power supply.


A modem that I recommend should *never* lock up during heavy dial-in/dial-
out/fax-in/fax-out operation, will properly communicate with most, if
not all, fax machines and modems out there in the market (which is hard,
because very many fax machine and modem vendors do not obey the proper
standards!!!). It means, you can buy the modem, turn it on, set it up 
once, and then never think about it again. It just has to *work*.


Hardly any Rockwell modem I have seen so far meets these standards (one 
does, and this is the Dr.Neuhaus Smarty modem, when doing fax sending). 
The ZyXEL 1496 series does, the ZyXEL 2864 does not. The USR Courier does
(for fax sending and data operation, it doesn't for fax reception), the 
USR Sportster does not.
