Abstract

A concept is disclosed regarding the method of underscoring via communication terminals. Instead of following the industry standard method for underscoring of lines/words/characters being transmit ted/received on communication terminals, a method was developed for increasing throughput by decreasing the number of characters being sent and taking advantage of the printing speed of the electronic printer. Whereas the standard terminals on the market today transmit a three-to-five character sequence for each character underscored, the Xerox word processing devices will transmit only delimiters of the field to be underscored.

A concept is disclosed regarding the method of underscoring via communication terminals. Instead of following the industry standard method for underscoring of lines/words/characters being transmit ted/received on communication terminals, a method was developed for increasing throughput by decreasing the number of characters being sent and taking advantage of the printing speed of the electronic printer. Whereas the standard terminals on the market today transmit a three~-to~ five character sequence for each character underscored, the Xerox word processing devices will transmit only delimiters of the field to be underscored.

~es

A. Industry standard IBM 2741 typically sends the following sequence for each character:

1. Character to be underscored
2. Shift to upper case
3. Backspace
4. Underscore
5. Shift to lower case

B. The Xerox word processing devices will send:
1. Begin underscore
2. Character string to be underscored
3. End underscore
