And, specifically, the COMREC error is that we sent RTN (retransmit the 
page) and got DCN (disconnect), which probably happened because the 
remote didn't want to retransmit in this call.  This is a common thing.

No.  The problem probably lies in a poor connection.  Of course if this 
is reproducible in Class 2 but does not occur in Class 1, then 
something's wrong with the modem which causes it to send RTN 
improperly, but I doubt that's the case.

Class2BUGCmd simply turns on and off the echoing of the +FHT: and +FHR: 
reports.  It does nothing with regards to how the modem interacts with 
the remote.
