I need to know how to set up the serial device to generate a signal when
the carrier drops.  I am writting the serail routines for my BBS and
don't want to have to do a CheckCarrier() type of thing all over the place.
Yes, I know about the CMD_QUERY, but that's not what I want.  If I did that,
I could set up a timer_request to check the carrier once a second, but I
would rather have it tell me when the carrier drops.  At least, it would be
nice if I could have a flag like SERB_CHECKCD that would enable checking of
the carrier and return an error of SerErr_NOCD if the carrier is lost.
 
Please CBM, PLEASE release the source for the serial device, and / or add
this capability...  It would make writting an AUX: device easier, a BBS
easier...  This is such a small change, and I request that you put it into
version 1.3.  We need it.  Gee, it would be nice to detect a SIG_HUP and 
deal with it.
