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...
