    Sorry about the previous posts on this subject but we've had trouble
getting our rn working right.
   Anyway, I have one of the v42-v42bis MNP5 Magic modems sold by MacProducts 
and would highly recommend it. The modem has a very nice metal case and completee LEDs on the front. The Rockwell RC2324AC chipset is used in the modem.
It has MNP1-4 error correction and V.42 error correction. It supports both
MNP5 and V.42-bis data compression. Considering that the Hayes 2400 V-series
sales at $450, this modem is a steal at $199. It even has a really nice 
feature I've never seen on any other modem. A trimmer control one the back of  
the modem allows you to adjust the impedence of the modem to match that of
your particular phone line so as to minimize "near end echo" that can make
the connection noiser. You do this by calling a friend who leaves the phone
off the hook after answering. Then you use the ATX0DT4.....4 command to
send a continous tone. The trimmer is then adjusted so that you hear the
tone at the lowest volume. Nifty...
