PDT 3200 Technical Reference Guide
CFGDEV.SYS
CFGDEV.SYS is located on drive B of the PDT 3200 unit. When CFGDEV.SYS is loaded by
B:\CONFIG.SYS, a logical character-based device called PARAMS is created. This device
receives programming strings that modify the conÞguration parameters that control the
behavior of several system components. There are three ways for the developer to send
programming strings to the PARAMS device.
¥ Bar Code Scanning Special bar code labels beginning with $+$- and ending
with EE can be scanned using any bar code scanning device. The PDT 3200
Product Reference Guide contains many useful labels.
¥ File Copy Files containing the bar code programming strings can be created
and copied to the PARAMS device. The PDT 3200 ConÞguration Utility creates a
Þle called BPARAMS.INI that contains all of the conÞguration settings.
C:\AUTOEXEC.BAT on the unit contains a command to copy this Þle to
PARAMS (IF EXIST c:\bparams.ini copy c:\bparams.ini PARAMS). You may
also create your own Þle containing conÞguration settings.
Example: Use D2 defaults with CTRL-ALT-DEL sequence disabled.
1.
Create a MYPARAMS.INI Þle with the following text: $+$-D2E00EE. D2
sets the D2 defaults, E00 disables CTRL-ALT-DEL.
2.
Copy MYPARAMS.INI to the PARAMS device using the following DOS
command: COPY MYPARAMS.INI PARAMS
¥ Developer's Toolkit API The API in the PDT 3200 Developer's ToolKit contains
two function calls that allow you to send conÞguration strings to the PARAMS
driver from within a C application. See CFG_Write() and CFG_Read() in the
Developer's Toolkit.
Attempts to create, delete, or modify a Þle called PARAMS will conßict with the PARAMS
device. You cannot eliminate the loading of CFGDEV.SYS except through the safe-boot
process.
