I have heard of very few owners that have had any real problems that were not due to either: (1) Failure to read the manual. This is NOT a Hayes modem, and some things are a bit different.

If you call a lot with high line charges and do a lot of file transfers, it could pay for itself quickly. But if you just spend time reading mail, you won't see much difference in speed ('though the MNP error correction may help a bit.) > What about problems? No problems here.

But if you just spend time reading mail, >you won't see much difference in speed ('though the MNP error correction >may help a bit.) > One word about file transfers: In the 9600 bps mode, it is divided up into one 9600 bps and a 300 bps channel. It automatically gives the higher speed channel to the direction of highest traffic. So if you use a file transfer protocol with small packets like kermit or xmodem with 128 byte packets, the speeds keep switching on ya. The result is that if you need to use kermit or xmodem, it's faster to use the modem in 2400bps mode. That way you get 2 2400 bps channels. However with Zmodem and Ymodem, the HST flies at 9600 bps. Some of my terminal programs have trouble keeping up with the incomming data using the 9600 and Zmodem. It seems to lose data and can't tell one incomming packet from another. But then it might be the unix system I am calling into. I can't be sure without more experimentation. The HST also has a 19200 bps mode that really only works on text. It sorta crunches text at the sending modem (like arc or zoo) and uncrunches it at the receiving modem. This doesn't work so hot when trying to transfer arc or zoo files because they are already crunched down. -- John Sparks | {rutgers|uunet}!ukma!corpane!sparks | D.I.S.K. 24hrs 1200bps ||||||||||||||| sparks@corpane.UUCP | 502/968-5401 thru -5406 A virtuous life is its own punishment.
