  Oops, sorry about the last message.  My finger got ahead of my brain.  :-(

  I had written earlier that if a voice call comes in to my faxmodem it
takes a long-time to recover.  After more investigation I found out the
modem do not generate the "NO CARRIER" message after the hangup.  I am
enclosing the traces.  Thanks!
