Select what "should* happen if a "DLE" occurs in the transmission stream of bytes? Nothing, the receiver will not read the DLE It should be escaped with a DLE The sender will need to configure the transmission not to send any DLE patterns as they are protected patterns. A DLE cannot occur in the data, the sender will not let that happen One dimensional Parity Bits can detect up to a 3 bit error in transmission. True False Checksums are still used today because they are resilient to errors and easy to implement. True False
