ACK NAK Error Handling
This item specifies the method the scanner will use to handle errors
detected while waiting to receive the ACK character from the host.
Errors include unrecognized host commands and communication errors
such as parity or framing errors. Choices are:
00 = Ignore errors detected (recommended setting)
01 = Process error as valid ACK character (risk of lost label data)
02 = Process error as valid NAK character (risk of duplicate label data)
