- Can anyone explain to me the differences (real or perceived)
- between different brands of modems? Flipping through Computer
- Shopper, typical prices I'm finding for a few brands are:
-
- US Robotics $550
- Hayes Optima $470
- Practical Peripherals $380
- Boca $260
- Zoom $250
-
- (Probably not the lowest prices available -- I didn't search
- that carefully.) All are (I think) 14.4k modem/fax externals,
- with V.32(bis)/V.42(bis)/MNP (or maybe missing 1 or 2 of those),
- so it seems like the basic features are the same. So what other
- significant benefits do you get from the more expensive modems?
-
- Are there really any differences in reliability? I've been
- using a Zoom 2400 baud modem for the past 3 years (one of the
- cheapest brands I could find at the time), and I haven't noticed
- any serious problems with errors, so I'm wondering what reasons
- there are not to get the cheapest modem I can find, as long as
- it has all of the protocols that I need. Has anyone with a Boca
- or Zoom 14.4k modem (or any other inexpensive modem) noticed any
- major problems?
-
- Also, let me just check some terminology:
-
- V.32 is a (protocol? standard?)
- V.32bis and V.42bis are data-compression schemes
- V.42 and MNP are error detection/correction schemes
-
- Is this right? (These are just my impressions from reading the
- little advertising blurbs for the different modems.) Is one type
- of data compression or error detection better than the other?
-
- Any help or specific modem recommendations would be appreciated.
- (The only things I really want are 14.4k and V.32. Everything
- else is up in the air -- doesn't even have to be external.)

- Thanks,
