If the value of <COUNT> fields are zero, an <EOT>, followed by the <BCC>, completes the message. The reader
may, at its option, use NULL for COUNT when transmitting.
For Protocols 1 and 2, if the reader detects an error in an incoming transmission, it will respond with a
“Communications Error” message. If the host detects a transmission error, it may request a retransmission. Both
protocols enforce a 100mSec timeout between characters.
For all Protocols, the host may, at any time, stop/start the reader transmission by using software “handshake”
(DC3/DC1) or hardware “handshake” (if enabled in EEPROM configuration) by controlling the CTS line.
