Remarks on program function
The device data for a PS2
keyboard can be updated, i.e. programmed, changed or cleared with this
program. Data which has already been stored can also be displayed for
information.
The interface and link to a
processing unit must be defined and the device-specific operating mode set.
Note:
If additional
devices, e.g. magnetic card reader, central lock, waiter lock, etc. are
connected up, the appropriate key codes must be entered in program (PS2
device data format).

information on programming a PS2 keyboard.
Remarks on data fields
The following description
deals with all available options for update of this basic data.
As with nearly all other
programs the following also applies here:
- The entry mask for this program may differ in
your MICROS Retail OSCAR POS program. Some data fields may be missing.
- There may be defaults or firmly defined
selection options for some data fields. These cannot be updated in the
current program.
- Fields with enforced entry defined are to
be found in the entry masks as are fields where entry is optional.
- If the data record is updated over several
pages of entry masks, the dialog window is reached by clicking on the
appropriate button with <Mouse key 1>.
- The same procedure also applies to call up
of another update program from this program.
- In some cases you may find so-called
"Switches" which are activated or deactivated by the user with
<Mouse key 1>, depending on the setting. Activated switches have a
dark top, deactivated switches are lighter.
Key code
Entry range permitted:
numeric 1 - 999999
First key code for the
start sequence of the device data.
The key code is entered
in this field. This is the code which is sent by the keyboard when a key is depressed.
We recommend that you set the debug level in program PS2
keyboard to 3 or 4
to allow the key code of an unknown keyboard to be ascertained
If debug level = 2 is set the key code for each depressed key will be shown in file "..\work\errlog", in hexadecimal format. The entry of the key code in this program must, however, be done in decimal format.
Followed by
Entry range permitted:
numeric 1 - 9999
Enter the key code which is
to be sent as the follow-up code by this device. The combination of both codes
defines the start sequence of device data. Often rare combinations such as “Strg-k”, shift-escape”, etc. are sent.
End code
Entry range permitted:
numeric 1 - 9999
Enter the key code which is
to be sent as the end code by this device. In most cases this value is the key
code of the entry key (65293).
If this vale = 0 the value
for the number of key codes which follow the start sequence should be entered
in field length.
Length
Entry range permitted:
numeric 1 - 9999
Number of key code which
follows the start sequence. If the length of the device data is variable, an
end code must be defined.
