Chapter 2 Program Instructions
Remarks, cont'd. tmp: is the printer's temporary memory, i.e. normally the DRAM SIMMs,
which will lose their content when the power is turned off or at a power failure.
Thus, do not use DRAM for valueable data that cannot be recreated. One
advantage of using "tmp:" instead of "c:" is that data can be written to DRAM
faster than to the flash memory.
uart1: is the standard RS 232C port.
uart2: is an additional serial port on an optional interface board.
uart3: is an additional serial port on an optional interface board.
wand: is any input from an Code 128 bar code not containing any FNC3
character via a bar code wand or reader connected to the wand interface.
Buffer size 256 bytes.
Each electronic key may contain several key items with different properties
(counter, lock, or storage). The device name calls all key items with the
corresponding properties, regardless if they are stored in the key circuit on the
CPU board or in an inserted external key. Each key item has a 4-character
name, usually appended by a delimiter (?) and a 4-character password. Also
see OPEN statement.
