type of controller currently attached to the system, lists the features
supported by the controller, and outputs the status of the controller
hardware (a self-test code).
Response: Returns an identification code up to 8 ASCII characters in the
following format:
<SOH>TtFfffSs<CR>
where:
Tt = Two ASCII characters that identify the controller type.
TP = TouchPen series of controllers
QM = Serial/SMT3 series of controllers
Ffff = Four ASCII characters that indicate the features supported by
the controller.
R = Indicates a resistive controller
V = Indicates the Serial/SMT3V series of controllers
**** = Indicates no additional features configured
Ss = Two ASCII characters that provide status information about
the controller hardware. The two characters represent one
byte. Each character is in the range 0 to 9 and A to F.
Table 12 defines the meaning of each bit in the status byte.
Each bit can be set to 1 or 0, where:
1 = Error
0 = No error
00 = No diagnostic errors (normal response)
