Driverless signal generating apparatus and control method thereof
First Claim
1. A driverless signal generating apparatus to be connected to a computer host, which has an operation system (OS) having an application program (AP) for the signal generating apparatus, the signal generating apparatus comprising:
- a signal generator for generating an external signal in response to external excitation; and
an interface controller, which is connected to the signal generator and is to be connected to the computer host, and has operation firmware stored in the interface controller, wherein;
the operation firmware simulates the signal generating apparatus as a standard device, wherein a driver corresponding to the standard device has been built in the OS so that the OS regards the signal generating apparatus as the standard device;
the operation firmware receives a first command outputted from the OS through the driver and makes the OS identify an attribute of the signal generating apparatus in response to the first command;
the AP may be executed in the OS to generate a second command, wherein each of the first command and the second command pertains to a control transfer command (CTC) for enabling control transfer; and
the operation firmware receives the second command and thus controls the signal generator to generate the external signal and to send the external signal back to the OS.

Abstract
A driverless signal generating apparatus to be connected to a computer host includes a signal generator and an interface controller, which is connected to the signal generator and has operation firmware stored therein. The operation firmware simulates the signal generating apparatus as a standard device. A driver corresponding to the standard device has been built in an operation system (OS) of the computer host. The operation firmware receives a first command outputted from the OS through the driver and makes the OS identify an attribute of the signal generating apparatus in response to the first command. An application program (AP) may be executed in the OS to generate a second command. The first and second commands pertain to a control transfer command for enabling control transfer. The firmware receives the second command and thus controls the signal generator to generate an external signal to be sent back to the OS.

12. A control method for a driverless signal generating apparatus to be connected to a computer host having an operation system (OS), which has an application program (AP) for the signal generating apparatus, the control method comprising the steps of:
-
simulating the signal generating apparatus as a standard device, wherein a driver corresponding to the standard device has been built in the OS so that the OS regards the signal generating apparatus as the standard device; receiving a first command outputted from the OS through the driver and enabling the OS to identify an attribute of the signal generating apparatus in response to the first command; executing the AP to generate a second command, wherein each of the first command and the second command pertains to a control transfer command (CTC) for enabling control transfer; and receiving the second command and thus controlling the signal generating apparatus to receive external excitation to generate an external signal, and to send the external signal back to the OS. - View Dependent Claims (13)
