- Over the weekend, bought a new modem to get faster service than the Intel
- 14.4Kb "satisfaxion 400e" modem I've been using. Got a Practical
- Perferrials 288MTII 28.8Kb modem. Seemed to work fine except it got
- slower than the Intel whenever I did a download from Netcom using Zmodem.
- Uploads were quick, but downloads were slow. Nothing in the PP manual
- about Zmodem or downloading. Took it back to Fry's (they have a reasonably
- decent return policy) and then got a Motorola 3400 "Lifestyle 28.8" modem.
- The Motorola works fine on Zmodem downloads, about twice as fast as the
- Intel. The above results when using Telix 3.22 for DOS. Which I always
- use (I have a unix shell account at Netcom, none of that fancy graphical
- interface stuff here :-)!)
- It's academic now, but I wonder why the PP did so poorly on zmodem downloads.
- Looking at the boxes of the two modems in Fry's, they appear to have the
- same spec's, data compression and such. Hard to believe it was a sample
- defect, as with most microprocessor based products, such a defect would
- make the entire thing DOA.
- Reason for choosing the PP and Motorola modems was that, in some modem
- performance tests done where I work (by a neighboring modem IC group,
- I'm in video ICs) these worked very well in noisy phone lines.
