Shift state of the keys

Communications link

(in LAN-support software

BHT-5000 (BHT-5000 Screen Compatibility Mode)
This compatibility mode makes the screen layout and key assignment of the BHT-300 series downward
compatible with the ones of the BHT-5000. Using this mode can minimize modification in source code to
run application programs written for the BHT-5000 on the BHT-300 series.
The BHT-5000 screen compatibility mode does not assure full compatibility. The transmission speed,
communications link type and others for the IrDA interface, for example, are incompatible. For
details, refer to the "BHT-BASIC Programmer's Manual."
Enabling the BHT-5000 screen compatibility mode automatically switches the current
communications protocol to the BHT-protocol.
