The modem is supposed to send the result code before turning on DCD.
Otherwise, how is the computer to know which characters are the modem's 
result code and which are the caller's keystrokes?

The instructions for the special getty should have said how to configure
the modem and port.  Either you can't do dialout through the same port,
or you can with a special setup.
