Intermec 6200 Reference Guide

The 4805 Endcap Printer is not supported by the PEN*KEY 6000 Series

Computers.  Remove any code that is specific to the 4805 Printer.

The RAM drive is now drive C, not drive B.
If CardSoft software is used, use only the CardSoft drives (E and F) to access the

PC memory cards.  Using drive A or B can corrupt the cards.
Applications using drive tables may need to change the file maintenance done

after communications.  Change applications attempting to move files from one

drive to another to ignore drive D (Flash, readĆonly).

References to COM3 must be changed.  On the 4000 Series, COM3 refers to the

same port as COM1, but ignores the modem control signals RTS and CTS.  INT

14h function 5, provided by 4000API.EXE, can ignore modem control signals on

COM1 when needed.
Remove any reference to internal modems for the 4000 Series.  This includes

turning on/off switch V+ (Norlib function NRSwitchVplus).
PEN*KEY 6000 Series applications can use PC modems.  See Adding PC Card

Modem Support (page 6Ć8).

It is important to remember that all variables lose their values when the

computer is reset.  Any information that is needed to recover from a reset must

be written to a file so that it can be retrieved.

Verify that the memory requirements of the application can be met.  On the 4000

Series, it is possible to achieve executable memory sizes of greater than 640 KB.

This is not true on the PEN*KEY 6000 Series, which uses ROM DOS 5.  Because

of this, and due to differing system software requirements, some applications

could encounter problems of insufficient memory.

For maximum battery life, power to system components should be carefully

managed.  Drivers provided in the PEN*KEY Toolkit, such as PC4800.SYS and

MININET.EXE, turn power on as needed, but they restore power to its previous

state when finished.  Therefore, applications should initially turn power off to

certain components.  For example: COM ports, the LAN adapter, and the touch

screen.  NPOWER.EXE provides this capability, or the Norlib function

NRApmSetPower can be used within an application (see Section 4).

// power off COM ports
NRApmSetPower(NR_POWER_OFF, NR_DEVICE_COM1 | 0xff);
// power off LAN adapters
NRApmSetPower(NR_POWER_OFF, NR_DEVICE_LAN_ADAPTER | 0xff);
// power off digitizer pads (touch screen)
NRApmSetPower(NR_POWER_OFF, NR_DEVICE_DIG_PADS | 0xff);
// power off Switch V+

NRApmSetPower(NR_POWER_OFF, NR_DEVICE_SWVPLUS | 0xff);
