CCID_ESC_GET_SET_GUARDTIME
This function code shall be used to set and get the character / block guard time of the reader.
The guard time is specified in terms of etus.
The buffer shall point to the escape code followed by the guard time structure.
typedef struct _GUARD_TIME
{
uint8
byGetSetIdentifier;
uint8
byGuardTimeIdentifier;
uint32 dwGuardTime;
} GUARD_TIME;
6.1.14.
CCID_ESC_GET_SET_EGT
This function code shall be used to set and get the extra guard time of the reader. The guard
time is specified in terms of etus.
The buffer shall point to the escape code followed by a structure given below.
typedef struct _EGT
{
uint8
byGetSetIdentifier;
uint32 dwEGT;
} EGT;

CCID_ESC_GET_SET_ATR_TIMEOUT
This function is used to change the delay (in ms) between the power-up attempts in the class-
A, class-B, and class-C sequence;
The buffer shall point to the escape code followed by a BYTE containing the timeout value.
6.1.16.
CCID_ESC_POWER
This function code shall be used to change the VCC level for the reader. The input buffer shall
point to the escape code followed by a WORD containing VCC value. The ICC will be reset to
the value given in the buffer.
