Controllable NT20S Functions

The statuses of the NT20S can be controlled from the PC by writing control data to
the "PT status control bits" of the PT status control area allocated in the PC
memory.

The PC status control bits remain unchanged if the NT20S status is changed with
the screen attributes or memory switches, which means that the statuses of the
PT status control bits do not match the actual status of the NT20S. For example,
the buzzer may sound even though the setting for continuous buzzer bit 13 is
"OFF".
In this kind of case, control the NT20S by using the PT status control bits.
