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.
