o For technical accuracy.


When A/UX starts up, there's a delay in the keyboard response: it takes
a couple of keystrokes before anything appears in response to the "login:"
prompt. Here's why: during the log-in sequence ("getty" to "login"),
/etc/getty waits one second after issuing the following log-in prompt
message:

Apple Computer, Inc. A/UX

login:

This one-second delay keeps noise from being passed to the "login" process,
ensuring that phone lines are clean before dialing.

To avoid the keyboard delay, just wait one second before responding to the
log-in prompt. It isn't necessary to wait one second after the other
"login" or "Password" prompts, because they're generated by the "login"
process not the "getty" process.
