<p>PROBLEM TO BE SOLVED: To actualize a communication system wherein a terminal-side communication device never has a writing range limited and a host-side communication device has no overlapping display area. SOLUTION: When it is decided that there are received stroke data (S302: Yes), a terminal ID included in the stroke data is detected (S304) and when it is decided that the ID is registered (S306: Yes), the stroke data are read out of a receiving buffer (S308); and the writing area indicated by the read stroke data is compared with the display area corresponding to the terminal ID (S310). If the received writing area projects from the display area (S312: Yes), the X coordinates of all the received stroke data are multiplied by a proportion coefficient (r) and the Y coordinates are multiplied by a proportion coefficient (r) to reduce the received stroke data (S314).</p> |
