Checksum Bit
If the Checksum Bit is 0, the controller does not check the validity of received
commands. If the Checksum Bit is 1, and the Checksum is incorrect in a received
command, error code '3' will be returned in the Acknowledge packet. Checksums
are always calculated and transmitted by the controller to the host. The host may
choose to ignore the Checksum or request the controller to retransmit corrupted
packets. See Checksum Byte, page 51.
Software Handshaking Bit
If the Software Handshaking Bit is 1, the controller will recognize the software
flow control convention of XON/XOFF (ASCII 'Control Q' and 'Control S').
If the Software Handshaking Bit is 0, software flow control is disabled. The
controller will not send ^S/^Q characters, and ^S/^Q characters received by the
controller outside a packet will generate an error.
Software Handshaking is disabled by factory default. For more information, see
Software Handshaking, page 53.
