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.
