VT100 User Guide
Fill characters are required to keep the VT100 synchronized with the host computer when the XON/XOFF control codes are not used. Table C-1 shows the VT100 fill character requirements for every receive speed at which the terminal is capable of operating. No entry in a column indicates that fill characters are not required in that specific case.
