Check with USR.  I'm not sure of the chip revision number but there
was a FREE replacement chip to callers mentioning the "Spiraling
Syndrome of Death".  This chip fixed that problem for me, also
allowing more frequent 26.4 connections.  In addition to a fix, this
chip adds a feature!  When to modems start slowing down to correct
errors because of bad conditions now they can also speed up if
conditions are favorable while connected!!!!

I run a near identical configuration and normally have no problems.

I did however have a difficult time getting the beta6 of netscape from
the netscape ftp sites.  This was a rather large file (over 2 meg) and
the download would start out fine and then slow down and die after
about a meg or so.  I finally switched to a less busy mirror site and
the file downloaded just fine (same phone connection to my local host).

I wonder if RAS has some sort of timeout settings that get invoked when
using a busy site (large files would cause a timeout?).

I actually run 3 separate machines with three Sportsters ranging from about
2 years old to about 8 months old (different S/W supervisor dates).  They
all work about the same for the sites I connect to.  I have never seen the
dreaded "sprial death" that has been widely reporded for older Sportsters.

I also have 2 of these modems (external) from the same EPROM date,
10/18/95.  However, I'm running in Windows 95 (and Dos) My problems include, 
dropping carrier, (esp. at 14.4) and freezing up; still TXing or RXing but not 
both.  These problems have plagued me for awhile now, and it's so bad that I 
can never play games over the modem with it.  I tried disabling data 
compression, etc until I got down to 14400/NONE but it still happened.  When I 
dug out my old Sportster 14.4, all was well.  It seems like my modems are 
infected "Spiraling Syndrome of Death" as well :-(
