  I am enclosing the traces for my continuing problem of the modem not
generating the "NO CARRIER" message.

  Thanks!

> why do you set you modem to class 0 (data mode again)?

  This is the default configuration for my modem.  The relevant line
from config.cuaa0 follows:

# The remainder of this configuration is included so that the
# modem "idles" in Class 0 while not sending or receiving facsimile.
#
ModemSetupAACmd:	AT+FCLASS=0&H1&I0&R2	# leave modem in class 0
ModemAnswerCmd:		AT+FCLASS=1&H1&I0&R2A	# force RTS/CTS after change
