CONTACT_GET_SET_GUARDTIME

This Escape command is used to get/set the Character/Block Guard Time of the reader. The
guard time is specified in terms of ETU. Once set, the new Guard time will take effect
immediately.

Input:

The input buffer contains the Escape code followed by an 8 bit GET/SET identifier, an 8 bit guard
time identifier and a 32 bit guard time value in ETU.

Output:

For Get/Set guard time, the output will be the Character/Block Guard Time value.
