Can I change a prompt after it has been sent?
Normally once the Terminal has received a prompt from the host, it goes to
sleep and waits (as long as it takes) for the operator to scan or key
something in response. The host cannot send another data entry prompt
without creating a "Sequence Error." However, you might want to change
the prompt to a slow operator or even locate a lost terminal with beeping.
You can do this using the "Automatic Check Back" option. You set a
predetermined interval (in increments of 5 seconds) of when you want the
terminal to send back a message "do you have a change for me?" If there is
no change, you simply resend the original prompt; if there is a change, you
send the changed prompt. (See Chapter 2
, Automatic Check Back).
