Command Codes
Comments
Some host systems automatically generate forms control codes
such as CR or LF after a specific number of characters. These
host generated forms control codes could prematurely terminate
the graphics command sequence. The Free Format command
allows VGL to accept incoming data as one continuous stream
even though the data stream may include host generated forms
control codes.
