Multi-Packet Option 1 - The host sends an ACK/NAK for each data packet during a multi-packet transmission.
Multi-Packet Option 2 - The scanner sends data packets continuously, with no ACK/NAK handshaking to pace the transmission. The host, if overrun, can use hardware handshaking to temporarily delay scanner transmissions. At the end of transmission, the scanner waits for a CMD_ACK or CMD_NAK.
Multi-Packet Option 3 - This is the same as option 2 with the addition of a programmable interpacket delay. See
Interpacket Delay to set this delay.
