1.  This release corrects only V.fC items.  The non-V.fC bug list is 
    essentially unchanged.

2.  An answer mode handshake incompatibility has been corrected.  
    You should see that we now connect properly with non-USR calling 
    modems.

3.  There are still more performance tuning and handshake reliability 
    improvements this week. Although you may not see the results 
    where you live, we now work on a much wider range of channel types
    having more severe impairment levels. 

4.  We are still not releasing speed switching, which means we stay 
    where we land during the initial handshake.  You will have it in 
    the next release--we promise.

5.  We have two reported problems with one particular manufacturer's 
    modem: a possible lockup if the modems attempt a retrain, and a 
    V.42 error control protocol synchronization failure.  We will 
    verify this.  

Now is when we really need your help.  We are looking for incompati-
bilities with other manufacturer's equipment, channel conditions we 
can't handle,  lockup modes,  situations where we work worse than 
others, things that bug modem users....  And, if we are doing a good 
job, we like to hear that too!

V.34 code is just ahead!
