Sure.  Use this command string to answer the call:

	ATX1D!,*70,;A

Most phone systems that allow *70 to cancel call waiting also allow 
you to cancel it on the current call by hook-flashing and dialing 
*70.  You're then placed back in the call (some require you to 
hook-flash again to get back, in which case you'd add "!," before 
the semicolon.  SOME phone systems require you to also subscribe to 
Three-Way Calling before this function will work.  This, of course, 
doesn't work with Auto Answer (S0>0), only with software-controlled 
answer.  You may want to set S8=1 so the commas only last 1 second 
instead of 2 seconds.  If you do this, then this whole process lasts 
only about four seconds, less than one ring cycle.
