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. 

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. 

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