This is not true.  When "SHARE" is selected "getty" uses CD to determine when
to lock the port (as you suggest it should).  In fact, when the modem and the 
tty are correctly set-up, this works just fine (after applying the 3003  
update).  I have corresponded with Rich on this very subject and it appears to 
me that he is using a back level "patch" that he is applying over the update.
This is not a good thing to do.  (This is so far... PURE CONJECTURE ON MY  
PART.)  Anyway, it works fine for me after 3003 with Telebits, and Hayes.

As far a "DELAY" not being used for dial-ups, please stop spreading this nasty  
rumor.  "DELAY" works fine with both dial-up and direct connect.  DELAY does  
use CD to control when to read and write the port, but it does not use CD to  
determine when to lock the port.  DELAY waits to see a character on the serial  
input buffer before locking the port.  THIS WORKS AFTER 3003.  I have tried it  
with both direct connect serial connections, and modems.

You call 1-800-237-5511.  I think you are wasting your time, this is not a  
software defect.     Sorry.
