5-3
• Keep in mind that if a Terminal has SIGNED OUT in mid-transaction, the
Base Station clears any pending message for that Terminal before it will
allow it to SIGN ON again. Make allowances to re-send messages or
prompts that were cleared upon SIGN ON if necessary.
• If a Base Station has a hardware failure, neither the Terminal nor the host
computer will be able to communicate with it. When the Base Station
comes back on-line, it sends a “Base Station Initialized” message back to
the host, letting the host know that it must re-initialize all Terminals and
pick up any incomplete transactions.
Operator Errors
• Plan on your operator walking out of range and going to lunch in the middle
of a transaction. What do you do with the data you do have, and where are
you going to start up again?
• Let’s say your operator is SIGNED ON and decides it’s time to take a
break. Instead of pressing the F1 key to SIGN OUT, he presses the OFF
key. Pressing the OFF key is OK (it will SIGN him OUT) but there is a
delay until the SIGN OUT is acknowledged. Because of the delay, the
operator might think he didn’t press the key hard enough and press it again
- this time actually powering down the Terminal before the SIGN OUT
was complete. If this happens, you need to plan to re-send the last prompt
to the Terminal when he SIGNs ON again.
