Re: US Robotics S-100 update
If there is anyone out there using the US Robotics S-100
modem, there is a modification that USR has available that you
might be interested in. The stock, older, USR S-100 modems
are absolutely incapable of talking to the USR 2400 bauds
effectively at 1200 baud (300 is O.K.), lots of noise on any
line. USR has a replacement crystal that they were willing to
send me at no charge that seems to eliminate (or at least
greatly reduce) the problem. They say that it is a higher
precision crystal than the old one. I still highly recommend
against the S100 modem for a BBS, but I must admit that it
makes a better BBS modem than a personal modem. My next modem
will probably be a more expensive Racal Vadic...
Nick.
