delimiter (col. 5, line 60 through col. 6, line 4).
In operation, the workstations monitor the network for
messages in which they are identified as the target workstation.
When this occurs, the workstation processes the message,
incorporating the data into the window display. Alternatively,
target workstations could generate a single information packet
for each change of display (col. 6, lines 12-23). Conference

42). Glaser further discloses that when a participant points to
any position on the whiteboard and presses button 38 on the

mouse. The second event is a mouse button-down and coordinates
