Responds with an 8-character identity string. This string identifies the 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.
QM = Serial controller
Ffff = Four ASCII characters that indicate the features supported by the
controller.
R= Indicates a resistive controller
V= Indicates the serial controller
****= 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 2 defines the meaning of each bit (LED flashes minus 1) 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)
