in this case, I am not sure I can disable it. I used kermit to dialout, 
after getting the connection,  exit kermit. (I guess at this point 
Carrier Detect (CD) is ON) I invoke pppd on cuaa1, but pppd complained
that the port is busy ( I suppose getty may mistaken that CD is actually
not intended for the getty but for the pppd).
