Does anyone know what versions of windows had this particular bug in the
PPP implementation?  Were any other systems affected?

I guess that the problem is not so much an issue in PPP (on the client PC
or at the ISP server), but the settings of both modems. To fix, you need

  +++ats2=255

on both: see e.g.

  http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/modem-hayes.html#MODEM-HAYES-ATTENTION

for details. (Also, there was a discussion on BugTraq at the end of
September 1998, maybe it would be useful to look in the archives?)
