STX. The ‘start-of-text’ character that is sent from one
communicating entity to another to signal the start of a block data
transfer. See ‘ETX’.
Subroutine. A routine that can be part of another routine. When a
main routine calls a subroutine, program control is transferred to the
subroutine. When the subroutine is completed, control reverts to the
instruction in the main routine immediately following the subroutine
call.
Swipe. The action of sliding a magnetic stripe card through a
terminal card reader. The Omni 3200 card reader has a bidirectional
swipe direction. The user must hold the card so that the magnetic
stripe is down and facing to the right.
Synchronous Communication. A system in which each event or
operation is constrained by signals from a clock. A clock provides a
constant time interval between bits, characters, and events.
System Mode. For the Omni 3200, the System Mode temporarily
disables Normal Mode operations, allowing you to perform local
functions such as downloads, diagnostics, and other operations that
cannot be performed while the application program is running.
To prevent unauthorized manipulation of data after an application has
been downloaded, the terminal requests the system password each
time the System Mode is entered. Upon successful password entry,
the SYSTEM= prompt is displayed. To enter System Mode, you must
press the [FUNC/ENTER] and [7] keys simultaneously.
Entering and leaving the System Mode restarts the application
program at its beginning, if one is active, causing any transaction in
process to terminate. See ‘Local Functions’ and ‘Normal Mode’.
System Password. A unique set of characters entered by the user
to access the System Mode local functions of the terminal. A default
password is supplied with each terminal. For the Omni 3200 terminal,
the default password is [1] [ALPHA] [ALPHA] [6] [6] [8] [3] [1].
