Okay, here's the modem list again. I would also appreciate comments
as to which modems have error correction, how long the guarantee is, etc.
This is the third time I've posted this article and I've still only got
comments from three people. Here is the article again with the comments
added.
Just out of curiousity, does anyone know the difference between a USR
Courier and a USR Sportster? Also, does anyone have any information on NEC
modems? Someone asked for it, but I haven't even found any for sale in any
of the magazines I looked in.
Okay, here's the list. By the way, all the modems on this list are
external. I don't have an IBM PC, so I can't use the the internal ones.
By the way, if anyone has any corrections or additions to make to this
list, just let me know.
Name Price
-------------------------------------
Anchor 1200 $120
Anchor 2400 $190
Not too bad - seems to work here.
Avatex 1200e $70
Avatex 2400 $180
Datatronics 1200 $120
Datatronics 2400 $220
Discovery 1200 $89
Everex 1200 (Evercom 12?) $99
Everex 2400 (Evercom 24?) $189
JUNK!!! bad!! For an outdial - ok. But when this modem answers at 1200,
it will not answer again at 2400, until power is cycled, or ATZ is sent
the modem - something Unix doesn't do.
Expert 12e $99
Expert 24e $189
Hayes Smartmodem 1200 $274
Ok.
Hayes Smartmodem 2400 $419
Multitech 1200 $225
Multitech 2400 $449
Very good. You set the talk rate to 9600 bps, and the modem will
translate to 2400/1200/300. Makes /etc/gettydefs easy. As well, with
the MNP 5 I have been able to get 380 cps out of this modem - not bad
for a 240 cps device!
Packard Bell 1200 $89
Packard Bell 2400 $169
Both models seem to be very good. I purchased mine 6 months
ago, and both seem to be going strong. The 2400 is used on
my unix box at work, making about 40+ calls a day. The 1200
is used home on my Apple //e to dial into all sorts of
machines in the area. The only problem I have had is getting
the two to talk to each other, but that is a setting problem
in my 2400, as I have talked to other PB2400's with the
PB1200. I beleive that both modems have 2 year warrenties.
I would recommend them.
Practical Peripherals 1200 $139
Practical Peripherals 2400 $199
QIC 2400 $139
Smar TEAM 1200 $90
I purchased a SmartTeam 1200 3 years ago for use on the
Apple. It died about a year later, was sent in and repaired
( under a 2 yr warrenty ). It then died again just after the
warrenty expired. Not recommended. ( I purchased it at
$240+, just after the 1200bps clones had come out )
Smar TEAM 2400 $190
Smart One 2400 $169
THE 1200 $99
THE 2400 $159
USR Courier 1200 $159
USR Courier 2400 $299
Not bad - seems to work ok here.
USR Courier 2400e $339
USR Sportster 1200 $129
I just bought one of these and it seems to work just fine. However,
I've only had it for a couple of weeks and it's really too early to
tell if it can hold up to the test of time. One thing I particularly
like about this modem is that it doesn't hang up when you disconnect
or turn off the terminal. Most modems I have used previously would
always disconnect.
Ventel 1200+ $239
Ventel 2400+ $359
Zoom MX 2400 $159
Zuckerboard 1200 $99

For their comments I would like to thank:

(Two other people whose names I lost; sorry, but thanks for your comments)
Thanks,

So you're saying your USR modem doesn't respond to the DTR line
correctly? That's hardly a "feature". It sounds like a
deficiency.

[...] I'm happy to see that Multitech modems are finally getting the recognition they deserve. The MT-224EH not only has MNP Class 5 support (error correction and hardware based compression) and Speed conversion (allows use of a single gettydefs entry), but also employs a very robust equalization scheme (which improves noise rejection) and all settings & stored phone numbers are backed up by battery. The price quoted by Chris is competitive, as the current suggested retail price is $649. But, as a service to the Un*x community, I market these excellent modems for $799/pair or $410/each. Hope I don't get flamed for making this public knowledge.

Okay, to you this may be a defect, but I have two computers and two terminals and sometimes there is a need to switch from one to another in the middle of a call. On the other modems I've used, the call would always be disconnected, making it impossible to use. Also, some computers use DTR for handshaking (instead of XON/XOFF) maybe not any REAL computers but some lesser-known ones do. Also, no one at all has responded to my third posting of the modem list. I'm beginning to think about forgetting the whole thing. It just doesn't seem like there is enough demand. Does anyone out there think it's useful at all? ------------------------------------------------------------------------------- Chris Ott Internet: chris@spock.ame.arizona.edu Computational Fluid UUCP: {allegra,cmcl2,hao!noao}!arizona!amethyst!

Boy, do I feel stupid. I totally forgot about the DIP switch on the
back of my modem (the USR Sportster) that tells the modem whether or not
it should pay attention to DTR. The user himself selects the modem's
response to DTR. The modem CAN be set to hang up when DTR drops. Sorry
about the confusion.
