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).
