This command is used to specify the character attribute. Once the character attribute is specified,
it is effective until a new character attribute or a new field attribute appears in the data stream.
Parameters can be truncated in the middle of a parameter sequence by specifying a final parameter
value, The high intensity bit is meaningful only in the default color mode and not in the program
color mode.
This response is used in the inbound data stream in response to the Read All command. It is also
sent to the host when the host issues the Enable CA Transmission command. The high intensity
bit is meaningful only in the default color mode and not in the program color mode.
