4 According co the text fil in che blanks with che best choices l An asynchronous serial data link is said to be character oriented C A. since the line is in an idle state C B because it has a duration oft seconds cc as information is transmitted in the form of groups of bits called characters C D. since it consists of 2 to 4 control bits 2. When the transmitter wishes to send data. it first C A. places the line in a space level C B puts the line in a mark level C sends a stop bit D. places a bit at logical 1 level1.
