The default output of the RS232 interface is tag data in ASCII format. If SecureMarkID® tags from
TagMaster are being used (recommended) the numeric identity is sent out. If other EPC tags are being
used the default output is the EPC data. The data is followed by CR+LF ('\r''\n').
A TAGP connection can be initiated by sending the HELOTAGP message to the reader. The TAGP
connection is terminated with the QUIT message.
