Does anyone have any hard facts (studies or whatever) about increased productivity using 2400 vs. 1200? I vaguely feel that, at the current prices, 2400 is worth buying new modems, but I'm not convinced enough to convince my boss, who signs the checks, and doesn't want to. -- ....!hplabs!faunt faunt%hplabs@csnet-relay.ARPA HP is not responsible for anything I say here.

I think my boss would find upgrading to 2400 bps modems easier if we could
trade in the Hayes 1200's for Hayes 2400's and maybe pay $200 (or less) each.
If we have to pay over $200 bucks to get the 2400 bps, then we may just sit
back and wait for the 4800 bps modems to come down in price. I really don't
think many people will throw away the $600 1200 bps modems just for the fun of
paying $800 for a 2400 bps modem, do you?

I don't have any hard facts; however, I DO know that it would be EXTREMELY difficult to go back to 1200. 2400 is just over the subjective threshold of "fast"; from home, I feel that full-screen editing is close to the speed I get at work. Please post any objective studies you may find.

There were some studies in IBM Systems Journal about one or two years ago on response time. The conclusion was (fuzzy memory here) that response times over a couple of seconds were bad for productivity. I seem to remember a factor of 4 (but I could be wrong). Baud rate is a factor in response time, particularly if you spend a lot of time paging through stuff like when reading mail, or scanning a program that you are trying to fix. Sorry for the fuzzy reference, but it was someone else's copy. w underwood

Most of the 2400 bps modems have automatic adaptive equalisation, like
the V.29 modems. In dial-through service, there is nothing more unsettling
and unproductive than those {ight {Psquigg{y brakce{s...
On an unrelated subject, why do I not notice the unsynchronized thingie
purported to cause right squiggly brackets on 1200 modems (at my home) when
using 9600 bps V.29 dial-throughs at the same home? We do large file transfers
error free (taking 2-5 minutes) all the time over these things.
