CMD_GETEMVER

Command ID - Get interface
version used by emulator
Description
This command is sent by the host to query which version of the emulator interface this device is
using. There are two ways to respond to this command:
 You can error out and return RSP_CMD_ILLEGAL. A properly-implemented
EMVER_EMULATOR_V1 device should do this. When the host receives the
RSP_CMD_ILLEGAL response, it will assume that the device is EMVER_EMULATOR_V1 and
treat it accordingly.
 You can respond with an RSP_EQEMVER response indicating the version of the emulator
interface that your device is using.
Response
Description
RSP_EQEMVER
Returns the interface version used by the
emulator
RSP_CMD_ILLEGAL
Request is not supported because the emulator
uses EMVER_EMULATOR_V1
